I can get some wire hanging cages for pretty cheap around here. I was wondering what size holes do I need for week old silkie chicks? Is it good to keep chicks on wire for a month? I then would move them to a grow out pen with shavings. Ohh and is there any way to put something on the bottom of the cage so that it wouldnt be wire? What do you do? I was thinking about putting a piece of wood over the wire and then put shavings on top. Any ideas???
