the BB cannot fly well at all. I keep my turkeys with my expensive chickens, Some dont. The risk here is blackhead and some other nasty chicken diseases, but its your call. Heritage can and will fly very well. and as far as turkey eggs go, the are so much better than chicken eggs. before you get any BB birds, please understand these are not meant to be pets, they will get extremely large, and 98% develop heart or leg problems if you do not butcher them. The also will not breed naturally as they are too big. I really suggest a heritage breed unless you are raising the BB for meat purposes. You could always clip a wing.
