Welllll, I tried the late night introduction into the hen house, which didn't work. The most dominant chick (a Delaware) of the 2 fidgeted around which irritated my big, low-on-the-pecking-order hen. Whereas, my submissive black Australorp quickly bedded down beside (but, not under) my dominant RIR matriarch. I closed the door and sat quietly beside. After about 20 mins of constant peeping from the chicks, I heard rustling and a loud chirp inside. I knew one of them was under attack. Sure enough, the Delaware was getting pecked at by my big LOTPO hen. I pulled them out…sigh. And, brought them back inside…sigh. Soooo, here I sit on the couch with my loving surrogate hen-mom (a neutered, male, Pit/Mix) with one of the chicks nestled in the pocket of my hoodie, while the other is fast asleep atop my shoulder behind my hair. Aaaaannnnd, as I type this, the Delaware just moved into the surrogate hen-mom's tummy. Sigh, they're very cute. But, I'd like them to grow and learn outside with the big hens. Help. What can I do? Try again tomorrow night? Do it earlier in the evening? Do it later? Glue adult hen feathers to them or pin coyote masks on them? Almost just kidding about that last idea.
