I haven't hatched any Cochins yet but I have hatched Silkies.
This summer, I had 3 hens sitting on eggs. Once the eggs started hatching, the two white ones hogged all the chicks and left none for the blue girl that soooo badly wanted to care for the little things.After all the eggs had hatched, the blue still had no chicks. I ended up giving her two that hatched in the incubator and stole one from the white girls.
My blue hen was a HAPPY girl!![]()
I can't imagine it would make much of a difference if you took a day old hatchery chick and gave it to a hen as long as the hen was broody? I'm not an expert! But that's what I'm thinking.
I know Silkies will sit on just about anything, it seems, not so familiar with the Cochins yet. Still learning.
Thank you

I'm happy to hear it!
