Hello All: New to this site....very nice. We have 6 pullets born in April or so and started laying in Sept of 2007. We have 4 Reds and 2 Black sex links. 2 of the Reds in succession (one week just after the other) have started to lose feathers around their bottoms under their vent, revealing pink skin. They are healthy, happy, and keep laying fine other wise and the first to lose the feathers has already grown more in. This is our first chicken experience and we have read all we can to keep them happy, healthy, and safe. We should note, we did get two very large (double-yolk) eggs recently but we do not know from which hen it was bestowed....but ouch, it had to hurt compared to the sizes of their regular eggs! Any advice or help would be appreciated.
