One of my Orpingtons started laying in February and was a strong layer all summer. In July, she laid a fairy egg shaped like a bullet and about the size of my thumb. Since then, she hasn't laid any eggs at all and She dutifully heads up to the nest box nearly every day but doesn't deliver (internal laying maybe?). She "squats" every time she sees me heading for the coop (which I find hilarious and my husband finds troubling). I have noticed that she occasionally has a very slight blue tint to the far back portion of her comb. . She is otherwise seemingly healthy. I have attached a picture - she is at the back, you can see her comb is slightly blue. Thoughts on what is going on and whether I will ever get another egg?
