I have 30 chickens....28 hens and 2 roosters. One of my roos is a Jersey Giant. Our roosts are 2x4 with the 4" side being the flat side for their feet. For the other 29 birds, it is seems fine. But, my JG roo is huge (12-13 lbs and he is only 10 months old ans still skinny!) and it seems like it is a mere stick for his size!! His chest is getting a red, dry patch where he is against the 2x4 (rounded edges, not sharp!). I think a 2x6 would be better, but figured I'd get ya'll opinions first before I go spend money! Any other suggestions are great too!!
