I have 15 black chicks and one yellow one. They are all a week old and share the same brooder pen. My yellow chick had pasty butt and in cleaning it off, some of the feathers came off leaving a bald spot. Next time I'll be way more careful Today I noticed two of her her pen mates peck at the spot. It's still small, but now it's red; a perfect target of red and yellow (in a sea of black and grey) for inquisitive chicks. Should I put Blu-Kote on it? Antibiotic ointment? Vaseline? I don't want to separate her out if possible... Oh Dear, what should I do?
