I have 8 week old babies I'm trying to integrate with my two adult hens. Right now, the babies are in a separate pen that is inside the big girls run. Last week, I gave them LOTS of protection. But starting today, the fence openings are bit bigger and big hens can get their heads in there to deliver a peck. But the babies can get into the middle of this 3' by 3' pen where they are safe. I've also let the babies out into the big girls run and the big girls have shown them that they are in charge. But nothing more. Probably because I was RIGHT THERE. I wouldn't DARE leave them alone just yet. But I'm FREAKING out about integration. My two adult hens are clearly not happy about these three new additions. How do you create an opening that is only big enough for the babies to get through? I tried this, but now matter what I do, my FAT BO who tips the scales just under 5 lbs can squeeze through. So do I just make lots of hiding places and go that route? Will the adult hens actually kill a baby? I'm really eager to get them all integrated but I also don't want to lose anyone so I'm willing to keep them separated for another month or so until they are a bit bigger. But it's a huge time synch and I'm just exhausted from raising these guys through the coldest winter I ever remember here. What a chore.
