We have about 5 chickens and 2 roosters - Rhode Island reds are great to start with. There is another breed called sex-link that are also great egg producers. Handle the rooster a lot when it is young so it is use to you, being handled and will stay calmer.
Roost is where they go to sleep at night.
The other is where they lay the eggs. We let ours out and they eat a ton of bugs, kids love them.
