My month-old coturnix are getting bald spots on their backs, between their wings. About a third, or maybe half, seem to have this problem. Some are also losing feathers from the backs of their heads. What's going on? Mites? Pictures below.
GAWD. Really? Already? I have another round of birds that are 8 weeks old and they aren't tearing each other up at all. I have the two groups separated by age, but as for roo-hen ratio, it's gotta be close to 50/50 since I haven't sorted them out. I was planning to keep them all together until 10 weeks and then butcher the roos and keep the hens for eggs.
