I had 3 quail hens already and at the weekend, I got 4 more (all hens). They're about 6 weeks old. They were in quite a crowded pen with males and pheasant chicks and they are quite skinny and missing the feathers on their backs. I think this might be due to overcrowding rather than mites but I am on the look-out. Does anyone have any tips about how to improve their condition? They've been eating a lot and drinking a lot of water since I got them, no sign of any eggs yet. Thanks in advance.
