I'm sure you do miss those girls and Cookie sounds like she was a sweetieI still miss my two girls that I lost, especially my special little mutt hen Cookie. I really miss her every day. I have a wind chime over their little graves where I buried them so I think about them when the wind blows gently.
As for the two severely injured ones, they are perfectly fine! Still have some missing feathers where the scars are but they are laying healthy eggs, clucking, scratching and doing their chicken things
And the rest are now back to being confident little girls too, they were very quiet for a few months but they are back on form nowmy head hen is now Waffle and is my cuddliest chicken. She likes a snuggle and is keeping everyone in check really well so it's worked out

I'm happy to read that the injured ladies have recovered and doing so well, sounds like they are quite happy.
Thank you for the update.
