We have two 3 week easter egger pullets and 3 other few day old chicks to add to our current small flock of Orpingtons. All the chicks and older chickens are pullets by the way - its still too cold outside for any of the chicks to go out for the night - but when it is time, how should I introduce them? About a week ago I had the easter eggers out with a few of the hens and the older one attempted to attack the babies. How can I ensure the babies will be safe? How big should they be before I try to reintroduce them again? Any help would be greatly appreciated!
