Some questions regarding designing breeder/broody pens. I'm looking at building a series of pens 8' x 4' to house 1 rooster and 1 to 3 hens for breeding. Or for raising chicks. Or to house 1 or 2 broody hens. How important is it that the roosters can not see each other? I was thinking of placing plywood between the pens but would rather just use wire as it lets more light in. Your suggestions are appreciated.
