Sometimes female quail will go "bald" on the backs of their heads/necks as a result of mating, especially if they are kept with a very active male and/or with just a male and no other females. Since mating is unavoidable, some feather loss is inevitable. The question is how much feather loss/balding is acceptable? The standard I'm currently using is that it's fine as long as it's just back of head/neck feathers, what's you guys' opinion on this? Also, do you know of any ways to reduce balding besides getting more females per male?
