Ok, I have an EE hen about a year old. Hasn't laid an egg for over a week, yesterday I found a litle thing that looked like it should have been an egg. It was mostly white but had some green to it, and looked like a busted water balloon. Today found what looked like a long stringy snot on the grass and checked the hen's backside. She had the same stuff on her rear. She seems like she is extra hungry but not interested in free ranging or sitting with the other chickens. What could this be??
