To update...
I attempted to put the babies in with the maran because she wanted to be near them while free ranging and the babies didn't mind her. The 1st night went well so I went to work, my boyfriend tried to let the maran out to free range but she wanted to stay with the babies. When I got home from work I let everyone out to free range. The babies were absolutely terrified of her and wouldn't leave my feet. After examining them I found several peck markings on my runt and some marks on the other babies. Instantly I decided this was not okay and am now using a extra large dog cage for the look but don't touch method with my 2 grown hens. I am undecided if I should keep her or rehome?
Hummmm
She looks a bit ratty.... have you looked her over carefully for parasites?
Very sad she was mean to the babies.
But it sounds like what you are doing is best.
As to rehoming.... if she can't integrate happily, that might be the best option.
