I have 5 coturnix quail hens and 1 rooster. They have all been raised together and are about 8 weeks old. Earlier this week, one hen had been scalped badly removing the feathers and skin. I removed her and she is recovering and doing well. Today however this morning I found 2 hens blinded in one eye. One is pretty rough. How do I figure out which one is causing this? Is this my rooster? He actually seems not that aggressive. Is this how all quail are? Any suggestions on these issues?
