I was just given a new hen and my other hens aren't accepting her at all. I know I just can't throw her in with the others, but for the past two days I've been letting them have supervised play time, and it's always cut short because the other hens are pecking at her, so. Do y'all have any advice on how I should go about adding her to the flock? Thanks so much! P.S. She's the same age as my others, but a great deal smaller, so she doesn't hold up much of a fight.
