I need some suggestions on how to introduce two 5 week old pullets to my small flock of two 2 year old hens. I want the new girls to be safely incorporated into the flock. I have heard that chickens can peck younger or weaker chickens to death when they are added to the flock. I just got my two new RIR pullets today. They are being kept safely in my basement in a large (2'x3') crate with a screened cover for tonight. After that I hope to have some suggestions on how to begin the introductions. I thought that I might use a 2' x 1 1/2' welded wire cage that I have so that they could be in at night in the hen house with the other hens. Would that be a good start? My hens do not free range (too many predators), so the enclosed run is an issue. It is 6' x 12' x 5' and not big enough to subdivide. Help!
