I have 3 chickens and one rooster. At night I put the two hens and the rooster in a smaller cage about like a rabbit cage (4 by 2 foot) and I put one in in another cage about the same dimensions which she only comes out of when supervised because she's picked on by the others. At night when I go out to put them up there usually sitting up on her cage I was wondering if putting roost up in their pen would have any advantages or if it is really necessary. They have roost up in the larger pen that I let them out in the day but they don't use them all that much. Thanks for any help.
