We have 4 chickens: 3 hens, 1 rooster. We bought them as 4 "female" chicks. Unfortunately, one turned out the be a rooster. To keep the rooster from making noise during the early morning we keep them in an isolated chicken coop with an automated door that doesn't open before 8:00.<p>They are funny creatures. They are basically little dinosaurs, with different behavior than other home animals. They are super efficient, rarely get food poisoning, and can eat almost everything. They are interesting creatures just to look at. I would always recommend taking chickens, but please keep in mind the following:<p>* They do make noise. The rooster is loud. But the hens make many funny sounds as well. When they laid an egg they make (loud) cackling noises. I don't mind this, but make sure your neighbors don't mind as well.<p>* Roosters don't like each other. They will kill each other if they have the chance! If you buy them as chicks, be prepared that you have to get rid of the roosters if you have more than one.<p>* Roosters also don't like me. I usually get attacked by my rooster when I enter the chicken area. I don't mind (I'm steeling his eggs, so I understand), but some people might get scared by this behavior.<p>* Chickens are social animals. Always keep at least two chickens together.<p>* Chicken feces smell. You must clean the area often.<p>* Hens don't always lay eggs. They get broody now and then. During the broody they only want to sit on the eggs, and don't have much interest in anything else.<p>* Hens and roosters have a hate/love relation. Roosters want to fertilize the hens all day long (which they don't like). But they also take care of the hens. A rooster will take care the hens stay together, he makes sure the hens eat first, he supports the broody hens, gather all hens together during nighttime.<p>* In the first two years they lay eggs almost every day. But when they get older they lay fewer eggs. After a year or five they stop laying eggs.<p>* I suggest to buy a food-o-matic (or similar) device for feeding. These devices make sure that rats and mice cannot get to the feed.
