I have 4 pullets that have been raised together and are now 3 months old and I am trying to integrate 2 new pullets that are 2 months old that were raised separately. I had the run divided for a week so they could see each other and interact but now I'm having some issues with the bigger ones bullying the 2 smaller ones in the run and in the coop! During the day they are all out in the run together and the 2 smaller ones are able to get away from the bullies. I put them in to the roost by hand at night when its dark so they can all sleep together and see each other when they wake up in the morning. The morning is when all the trouble starts from the minute I open the roosting box the bigger ones start picking on the little ones and I have to move them to the run so they have somewhere to escape. It bothers me to see the 2 smaller ones terrorized and ostracized by the 1 month older hens. How long will it take before they all get along and start hanging out together?
