So, I am beginning my flock integration process today. The bigs and littles have been able to see each other through the screen dividing the front and back half of the coop for about 2 weeks now. I am a bit worried at how they'll all merge and am hoping for no blood shed. My big girls are very docile so I have big hopes
. What I've done is taken 3 of the bigs and put them in with 12 littles (ranging from 5-10 weeks). The littles are about half to just over half the size of the bigs. So far, the bigs just seem to be interested in the new run and only occasionally send the littles running for cover. The littles can get away very quickly.
Has anyone tried integrating like this before? If so, was it successful? I am a bit worried about sleeping tonight. When they all come in to roost will there be WW3 or will they just all settle in? Should I leave the doors open until they're all settled so that they can get away from each other if necessary? And finally, will they wake up in the night and have a fight? Thanks for any help.
