Can I ask how this turned out? Did you hatch some and how was the process? I'm thinking of doing the same this spring with my buff orp roo and barred rock.
@AmyLynn2374 so did you just let the chicks stay in the coop with the rest of older flock from a day or two old? No need to protect them from the other hens?
My first broody, my jap bantam, was a great momma. During the incubation process the other hens would push her off to lay their eggs, cause heaven help them if they find their own nest to lay in, but once they vacated she would go right back to her egg. Of course I had them marked so I checked twice a day and took out new eggs. I candled so I knew when they internally pipped, so I slipped her in a cage, right there in the coop, where she was sitting and closed her in so the other girls couldn't mess with her or chase them off while they were hatching. After they hatched a kept the cage closed for the first couple of days then opened it so they could go in and out into the coop at will. She did take them back into the cage every night. She did an excellent job keeping them protected and had no issues whatsoever ever.
My second broody, my Spitzhaubens, hatched her two out about a week later. I could not cage her even at hatch because she would leave the nest and pace the kennel letting the eggs go cold. This was mid October in Northern NY, so it was quite chilly. Within the first 24-48 hours she was out in the run scratching, one baby missing, the other trying to get underneath her for warmth and she kept kicking him away in her attempt to scratch the ground. I ended up taking him away from her and bringing him in to brood him myself. I never found the other chick, not even a body. She did become an awesome "Aunt" to the Banty' three and stayed pretty much with the Banty and the older chicks.
The three that hatched by the Banty grew up in the coop.
How well they do differs from one momma to the other and the overall personalities of the flock. I have 2 8 month old silkies that are broody right now. Against my better judgment I decided to let them be, one has 4 eggs I let her have Thursday night, the other went broody Friday night, and this morning she had one egg under her so I left it with her. We'll see what happens. Worst case sceneries I bring the large dog crate in and they go in that.
