I have 2 hens, 3 pullets and 1 cockerel. The young birds will be a year old in a few weeks. They are all starting to get bare spots on their backs. I have looked and don't see any evidence of mites or lice. I have scrubbed the chicken tractor and dusted with both sevin and permethrin. I plan to scrub it again this weekend and dust all the birds. I may do ivermectin, too, just to cover all my bases. Watching the cock, he's not overly rough although he does favor Maude and Bertha. I did notice that, for some reason, he grabbed 2 birds by the nape of the neck several times when not breeding--I feel like he was warning them away from a certain spot--he was not allowing any of them to get at the spot where my hose reel is (maybe a snake under there?). So, I don't think they are being beat up in any way. I wasn't thinking it could be a molt yet (maybe the older girls, but not the younger). but it's been awfully hot.....Is there any way to tell if it's a molt? Would I be seeing lots of feathers on the ground? and maybe incoming pin feathers? I'm not seeing any of this.I can whip up some saddles if it's the heat or breeding, but like I said, it's hot and I don't want to make the heat worse. They have almost 3/4 of an acre to range on during the day, then the entire 3 acres when I get home at 5 until bedtime. Lots of bushes, trees and places to get in the shade, a steady source of fresh cool water. Or should I just keep dusting them?
