I recently lost some birds due to a raccoon. Left with only three birds, we are getting more! The babies are coming at the beginning of August. Hoping to introduce the 7 new birds when they are about 3 months. Wondering if there are going to be problems with the older birds, or no because the older ones will outnumbered by little ones. Wondering what people have experienced having more little birds than big ones. there is also no rooster, they free range for a few hours a day, have a fenced in large yard to play in all day and the new improved critter proof coop is spacious for the birds to have plenty of room. Thanks for your help!
