They will be started pullets 4 months old. The firsts thing will be putting them in a building all their own except for 1 of my hens and leave till I am comfortable that they can be integrated with the others.PG - on the Heritage RIR - Will these be started pullets or chicks? If started, how will you integrate them in with the existing flock?
When I move them in with the others I will at first put them right in with the others if that does not work out due to to much fighting. I will have a run built inside of my existing run about 8 ft X 12 ft with a small coop just big enough to give them room to sleep in it. Let them live in there a week or so Till I feel comfortable. Then start free ranging them with the main flock and then hope for the best. I'm sure there will be some fighting as long as they don't draw bad blood I won't worry about it because it is natural.
So I would say about 2 months before they meet the flock. 1 month before I get them and 1 month here.
