I had my uncle looking for a coop for me and he went to an auction and found this. Its a rabbit cage. I live in Pennsylvania and the winters are cold. I would appreciate any help in how to make this a better coop for my silkies and be warmer for them. There is wood on half of the floor. Shoud I add wood to the rest of the floor? I thought about putting plexy (sp) glass in the front of it. There is a door on the side. Any idea's on how to close it in but still give them light. I will be building something around it so they can come out but not be able to free range. I have 14 silkies do you think this will be big enough?
