My 21 week old SS has not laid yet, but has been squatting and singing the egg song for over a week. This morning I saw thick yolk droppings on the floor. It is coming out of my SS. She has been pretty irritable the past two weeks, but I think it's because she needs to lay an egg. The SS is walking, eating, and drinking normal so far. I do give them oyster shell and I see her eat it frequently. What do I do? Do you think she broke an egg shell inside? Her belly feels normal.
