Hi everyone! We have a flock of 6 chickens all about 13 months old. 2 buff orpington pullets 2 light brahma pullets 1 GLW pullet 1 GLW rooster We just got 2 americauna and 2 black australorps chicks that are only about 4 days old and are inside under the heat lamp like usual kept %100 away from anything or anywhere the other chickens have been. Question is, how and when do I start to introduce the babies. Do I wait until they are the same size... Or do I just let them get old enough to be outside and then keep them separated through a fence so they can see each other for a while? I've done some research, but it would be really nice to hear from real people with experience! Thanks so much everyone!!!!
