Rooster Problems

Updated: Dec 27, 2022

Bad rooster behavior is one of the most common issues faced by backyard flock owners. Roosters can be aggressive and territorial, which can lead to stress in the flock as well as injuries for the birds and even humans. In this post, we'll take a look at how to recognize and handle rooster aggression and the problems associated with poor rooster fertility like a pro.


Aggression is probably the one problem worse than crowing at 4 am. Aggression is especially problematic if you have more than one rooster in the flock. Aggravated roosters may also turn their aggression on hens or other animal neighbors if they become provoked and cannot get rid of the frustration.

Some of the telltale signs of an aggressive rooster are pinning other chickens, chasing them away from food sources, attacking other roosters, your flock, or even you. It is important to intervene early when seeing signs of aggression among your flock, as it can lead to long-term issues if left unchecked. In some cases, rehoming may be necessary in order to avoid further harm coming to your flock or yourself.

Handling rooster aggression requires an attentive approach to diagnosing their specific problem. The solution to your rooster problem will differ due to the rooster’s age, breed, and your rooster-to-hen ratio. For example, fighting between male birds is intense and often fatal. If you don’t have enough hens, don’t keep roosters together. Their aggressive behavior is also amplified by the start of the mating season in spring.

Heavy breed roosters, like Orpingtons and Barred Plymouth rocks, usually do well managing 8 to 10 hens where a lighter breed, like the leghorn, copes really well with 10 to 15 hens. If you have less than 5 hens per rooster, you should reconsider since your roosters might start fighting over who gets to mate with the hens.

The Henpecked Rooster

The alternative is also true, if you have too many hens for one rooster, your rooster will become henpecked, lose weight and condition and suffer from lowered fertility. The term "henpecked" simply means he’s trying to mate too often, unable to keep up with the demand and thus cannot produce enough sperm and has no time for eating. All in all, this is a very bad thing for his health and may decrease the quality of mating progeny.

Addressing Poor Rooster Fertility

There are three things to consider if your eggs continue to be duds.

The first is to make sure your rooster is getting enough water. A rooster deprived of water for more than 24-48 hours will have lowered fertility.

The second thing is to consider his iodine intake. If he had access to any foods containing iodine salt, you might want to remove this feed or replace it completely to avoid lowered fertility in your rooster.

The last consideration is to watch what you feed your flock. If a rooster eats any moldy foods he is sure to show a reduced sperm count and then struggle to fertilize your hens. The last thing you want to worry about after all that is a broody hen!

Solutions to Bad Rooster Behavior

In general, increasing the amount of space the rooster has access to makes it easier for them to establish their own territories and also allows for better socialization.

However, keeping roosters separated from other hens is essential to prevent aggressive behavior among your flock. Roosters are naturally more territorial and can become easily dominant if placed in the same area as the hens. Separating them allows for less competition over resources and keeps them from fighting for dominance in a small space. When keeping roosters separate, it’s important to give them their own feeder, dust-bath area, places to perch, and plenty of room to roam. Additionally, providing enrichment activities such as toys or treats can reduce boredom, which could ultimately lead to reduced aggression.

If attempts to improve living conditions and provide enrichment for your flock don’t reduce aggression among the chickens, then it may be necessary to remove an aggressive rooster from the flock. Doing so can be difficult and is not ideal, but it is often the only way to ensure that the other birds get along safely. When removing a rooster, it’s best to ensure he will receive quality care in his new home as this will help alleviate any guilt you may feel. Additionally, if you are able to find another owner who has their own flock, it can help make the transition easier since the bird will already have established pecking order behaviors. Always make sure that proper safety precautions are taken when handling an aggressive rooster and that he is rehomed in a humane manner.

Getting the Rest of the Flock In Line

Fortunately, there are several solutions for preventing or correcting bad rooster behavior. The first step is ensuring that your flock has enough space to spread out and avoid overcrowding. Provide plenty of appropriate places for roosting, dust-baths, and perches so they don’t need to compete for resources. Also consider feeding systems such as feeders off the ground, to help prevent fighting over food. If a single rooster is causing problems in the flock it may be best to rehome him so he can start his own flock, leaving peace in yours!

In addition to introducing better living conditions into their environment, you may also want to provide additional enrichment opportunities such as toys or treats that promote healthy pecking order behaviors instead of aggression. For example, hanging a cabbage from a string can give the whole flock something fun to do together without getting into fights with each other and lessen the chance of rooster troubles. With adequate space and sufficient activity, you should find yourself with a happy and peaceful backyard flock!
