A couple days later another Minorca ended up with same head wounds but much worse. I have them both together recuperating now and both I think will survive.
I just want to share the following with you because we all learn from each other and I think all this is my error in changing feed type (same company - Olsens brand - just different form)...here are my thoughts/observations...
I think Roger must have got to them and then other hens got to them to pile on as chickens are prone to do to an injured flock member. I think they are all "hangry" because I switched thier food to crumble/pellets mix instead of just crumbles and they hadn't been eating much. I started giving them wetted-down pellets and they seem to really go for that so hoping this hangry bunch is getting over this!
I was also waiting to see that they are over this so I could integrate the new NN into Rogers's egg laying flock. So hope to start that in next few days, also working on major work deadline so this may slip again.
My DH also fixed the second part of the fenced run in case it is a predator. There are many fires close by just over the hills in wild areas of Paulden so good to shore up in case predators escape fires and head this way.
And planning how I might evacuate all these flocks if it came to it. I have enough crates to keep all roos separate, Polish separate and then 2 injured separate, then the rest all go in back of truck all together with camper shell. Dogs with me in cab and GO.
