You're doing the best you can with this situation.I just went to check on them. Lizzy seems unphased by her injuries. She's the one I didn't notice because her darker feathers hid the blood initially. Eowyn was still sitting there shivering but her sisters were sitting with her. I picked her up to try and get her to drink some water and she definitely has pep in her still. She's a fighter! When I picked her up, the other 2 went over by mom and once I put Eowyn down, she went by them. Millie seemed to begrudgingly let her underneath. I'm going to give it a little time and see if Millie takes care of her. The wounds are cleaned and sprayed with Blu-kote so they won't be as peck-worthy. I am so over today!
If the separation gets worse, it'll probably integrate with the flock when it gets older just fine.
