Oh wow, there's a whole second page of responses I missed when I posted last.
Ah, I was thinking of increasing her protein mainly, but grower would be better? I'll check my bag, and get the grower, I need to make a feedstore run tomorrow anyway. I have polyvisol without the iron, I wasn't sure if I should give iron to the poultry because that's who gets these vitamins.
Her head does look like a Sebastopol. Her wing feathers are breaking off, and broken, many of them, so dry and dead looking. Many have come out and have no flesh in the quill part. They do not lie flat. I've yet to see her wings fully extended, but something is funny about the way the feathers lie. She has short feathers on her body but a few of them are "curly" and in general, her feathering is not real thick. I can't tell if it's a molt or not.
Like I said before, I didn't seen any poultry feed other than scratch sprinkled on the ground. Maybe she got depleted after this last breeding season. She looks "rode hard and put away wet".
She'll look MUDDY in no time around here. If she is Sebbie or part, thank goodness she isn't festooned with curly long feathers in all this rain and muck.
