2 year old silver laced wyandotte is lethargic since last night. She didn't sleep on the roost, instead sitting on the droppings pit. I had to make her get up this morning. She isn't interested in a treat. Yesterday in the nest I found a soft shell egg that had been mashed flat and in another nest one egg looked like it had yolk on it. I don't know if those clues are related. I checked her vent and crop and can't find anything unusual. Her comb and wattles are very, very pale. What should I do?
