I'm trying to introduce my 3 ...8week old pullets to my established 2...5 month old laying Leghorns. They are so mean. I tried to get them to roost together last night to no avail.I know eventually they will be large enough to hold their own. But for now they have a cage on the outside of the little brown hen house. I'm thinking of throwing the big girls out tonight and letting them roost under the tree.What's a hen Momma to do?
