We are relatively new to raising chickens. We inherited two chickens that are approx 1.5-2 years old when a family member moved. We love having chickens and decided to add to the flock. On advice from the feed store, we got 3 new chickens. When they were about the same age, we put them together. They have been in the same coop for about 3 weeks now. Sadly, one of the little chickens died (dog attack). When they are in the coop together, the little ones stay on the perch, all the time. They will get down to eat and drink when the big ones go out of the top part of the coop. Will they ever get along or at least be civil? Also, the little ones are not laying eggs. They are 5 months old. I know chickens don't lay as much in the winter. I'm worried that the big chickens will never let the little ones into the nesting box to lay their eggs. Thanks!!
