Thanks BBH53.
I don't have a hair dryer, but I can keep her inside (after a bath) with the heat on? Use lot's of dry towels...and keep her warm...?
I read while trying to figure out what is wrong with her egg laying that mites and lice can disrupt a hen's egg laying (and even cause shell-less eggs - or no eggs at all...I think the mites and lice might be so tormenting, that is can cause a hen to stop laying or to prematurely lay). And it lists the causes of shell-less eggs and internal and external parasites is listed as one of the causes. Here is the link:

I thought it was possibly due to a lack of calcium too - and she's had access to oyster shell from the day I bought her...and I can not tell that she knows to eat it either...I haven't seen her eat it - she had to learn from my rooster how to eat a lot of other foods that she's never seen before...it's entertaining actually to watch my rooster teach her. lol
