The mottled pullet seems to be turning more white. She is changing rapidly. Maybe she's an unusual recessive white?
She did get pooped on because she likes to sleep on the floor like a dummy...
love to see her when she is fully mature , maybe it is a mutation , your line has been in isolation for quite a white now .
she is stunning by the way
