no, please do the birds a favour and DO NOT mix quail species. as a rule of thumb, they all kill each other. the bobs kill the coturnix, the chukkar kill the bobs, etc... except for a few lucky exceptions. i repeat, DO NOT MIX QUAIL SPECIES. and otherwise, either decide on bobs or coturnix, if you want doves to brood, go for something bigger like ringneck doves. were i live anyways they are really common, you can buy them in a variety of colours almost anywhere. and doves need perches, anything from 5ft-the top of the aviary, lots if possible, and a couple of platforms/nest box type things. if you want to go elegance, try diamond doves but they are awfully small. the doves can become quite tame, to the point of them landing on your hand to eat food, but that's about it. don't push it with the numbers, get 1 pair, by this time next year you'll probably have 10 doves. I cannot stress this enough only one species of quail per pen. i recommend coturnix as they are easy to keep, calmer so they won't scare the doves, and unlike the bobs they wont compete aggressively with the doves for space. hope this helps!
