The story- I bought 2 Araucana laying hens about 3-4 months ago. The smaller one of the two started laying straight away, the second larger one hasn't laid a single egg up until about 1 week ago when she laid just 1 egg but since then she hasn't laid a single egg but a couple of mornings she went up into the nest boxes and sat there for a bit but then gives up. She isn't molting and isn't POL. If she is egg bound then how can I test it and then treat her for it???
