Hmmm, well, the Momma Hen sat on her nest and hatched her chick in a cornered off section of the main coop, so the others were familiar with them from the start.
When the chick was 2 weeks old we moved both it and it's Momma out to a larger, separate coop outside the main run. This was done primarily to give them a bit more space and some privacy, and let the chick experience sunlight and see the yard. From inside their pen, they could also see out to the rest of the flock while they free-ranged.
I make a concerted effort every day to offer a treat of scratch to the roo and the rest of the girls in the afternoons. This is done along-side the coop where Momma and her chick are, and they too get a scratch treat. So, they all kind of have afternoon tea together, and can see each other though the wire of the coop.
No-one has ever lunged at the wire of the coop to try and get to the chick, and I assume Momma would keep an eye on him/her? My big concerns are the chick getting pecked at, or my cat getting her - she has a real killer instinct. If I locked up my cat in the late afternoon, and let Momma and the chick out with the others for an hour before dusk, is she likely to take the chick back to their private coop? Or would she follow the roo back like the good old days, and leave the baby stranded out in the yard?
