Lovely Easter Egger pullet hen!
One of my favorite "breeds" and can't go wrong having one.
Skip the scratch (or keep below 10% total intake since it's deficient in nutrients).. provide oyster shell free choice on the side of your crumble..
Give her a rock or brick to hone her beak on if needed.. looks like the top might be a little long??
A tub for dirt bathing will also offer some natural grit.
What I see look like chicken wire and NOT 1/2 inch hardware cloth.. two completely different beasts with hardware cloth ACTUALLY protecting from grubby raccoon paws that pull chicken heads off through chicken wire. I could be mistaken about what I'm seeing though.
Thank you for offering her a safe shelter, food, and care!
Mutts is kind of an ugly derogatory term.. that doesn't give ANY credit to hybrid vigor but acts like inbreeding to get "purebred" is a good thing. it doesn't bother me either way.. since I KNOW the truth about "breeds".
BUT it's much kinder and maybe even more appropriate to call them barnyard crosses or backyard mixes.. If only I could ALWAYS be more kind.. but I am practicing!
