I would put the chick in with her. It will have a better chance than if you raise it in a box in your kitchen and try to put it out there when it is a half feathered stranger and has no hen protecting it.Thank you! She is an austrolorp. A great mother but not sure how welcoming she would be of the new strangers. I’m not sure whether to brood them myself and work on integrating later or try to integrate under the Broody in under 24 hours hard decision.
