Hello. I have seen pigeons at swap meets, farm houses, and even the zoo and they seem so freindly and amazing! I REALLY want to buy two. My question is, if the pigeons are given the correct housing at the top of the coop, can they be kept in with the chickens? They can fly up in their own area but also go down to see the chickens if they want. They can also go outside and fly in the (completely) enclosed run outside. Can they be kept together? If they can, will they exit through the chicken door (on the ground) to the run?
