Updating this thread, sorry for 'bumping'.
So, a month after, the pullet is happy and healthy. She free ranges, unlike her previous flockmates who are confined to their run. Now, there's one problem with this wonderful pullet of mine - since she has been away so long, none of the other hens recognize her. Further, she still has a bald patch at the top of her head where the skin was ripped out. Is she now in a similar situation like my cat?
My cat is the 'roo' of the flock at night, he deals with racoons, other cats, etc. and has several 'battle' scars, the most notable being on the left side of his face where is torn away by a coon and then stitched up to force the skin to join again. (This particularly injury happened twice btw.) However, he only has a touch of fuzz. Similarly, the pullet is now sporting a bright, pink patch on her head, just under her comb. When can I expect feathers to come in?
