Hi, I am a chicken newbie (in adulthood anyway!) I have 6 RIR peeps that are a 8-9 days old now, not exactly sure. They are in a brooder in my garage and are on growing mash and chick grit. A few of my chicks have featherless spots, usually just one spot per bird, no bigger than a quarter in size. They're in different spots on the chicks, but I think on a few they're on the crop. Any ideas on this? I'm sorry if this is a repeat post, I couldn't find anything similar. My peeps did get into a bit of veg oil, so could the feathers just be stuck together? My fuzzy butts are bald butts!
