I have two modena pigeons and they live in a spacious cage. It's 6 by 6 and about four feet tall. I was wondering if it would be OK to keep a couple of bantam hens with them. Ideally they would free range every day. Would this work? The modenas are very friendly and have lived with my small owl pigeons before and they never hurt them (except they did chase them out of their nest box once ). Thanks!
