I found some 6-8 week old coturnix for $1.50 a piece, but they are losing the feathers on their backs. The seller says it is because he doesn't have a light bulb out there for them. They are being kept fairly crowded in a wire cage out in a barn- no sunlight. Otherwise they look healthy besides their bare backs. I think I read on here that overcrowding can cause them to lose feathers. Is that the more likely reason for it? Would any of ya'll buy birds in that condition?
