really,so I have to separate them
Some species can be mixed, it's usually a hassle but it can be done, but not quail. Any other species will kill them. They're dead bottom of the food chain.
Partridge should be separate from most species, though strangely they seem to get along with pigeons reasonably well.
Pigeons should have a separate loft/sleeping area from chickens. They can share the same yard as chickens provided they have roosts they can fly up to when necessary. Plus they need different feeds, so their feed will have to be either high off the ground where the chickens can't reach it or inside their loft.
Guineas can be housed with chickens but they have a tendency to chase after them and pull their tail feathers, so they should have pinless peepers applied in most cases.
My suggestion would be to start with one coop, one run, and one species. Chickens would be ideal. After you have had experience keeping an easy species, consider adding another one (preferably in a SEPARATE coop and run, as running multiple species is a massive hassle and usually a worse situation for the birds). Keeping multiple spruces is no walk in the park and should not be a project taken on by a first timer.
