I have 3 full grown hens and a coop for them but I now have 2 10week old chicks and the hens DO NOT like them! As of now the chicks sleep in the house and they get put out side in r pool(no liner. Big sand box) . its giting cold and I am going 2 try and build a small coop so I can get them out side but also s slowly start giting them used to each other. does anybody know how to make a small coop with wooden pallets?
