After doing some research I'm pretty sure that you can mix them as long as you have a rooster of both types( I guess so that a bantam rooster can mate a bantam hen and the same for standards). However, if I got bantams I would only get two or three hens. Would this work? My fear is that our standard cockerel would try to mate a banty and end up hurting her. Our cockerel is a Rhode Island Red, and doesn't mate the hens too often, but I'm still worried. The hens are docile. Any answers, tips, or suggestions are appreciated.
