Help help! I have about 10 chickens (out of 20+) that are about 70% naked due to feather loss. It's not a molt, as these are less than a year old. It's not picking, but I'm not sure what is going on. They're losing feathers on their neck, thighs, chest, and completely around their vent. I've made sure their coop is clean, and even dusted the coop with Seven in case it's mites. I had noticed they had blood in their stool and on their vent, but I regulated their food (scaled down the scratch feed by QUITE a bit) and that seems to have gotten better there. I'm concerned this isn't a molt, and certainly not picking. Something seems wrong. Please guys, do you have any ideas?? They're starting to look like turkens!
