I have 4 hens, a Barred Plymouth Rock, Red New Hampshire, Blue Wyandotte, & an Ameraucana all are 28 weeks old, 3 of them have been laying daily since they
each started. my 4th girl, the Ameraucana has been going in and sitting on the nest everyday for a week but has not produced any eggs. She is active & eating
well, no sign distress or straining. I have measured the distance between her pelvic bones & that is fine however the distance between pelvic bones & Keel is
only 3 fingers instead of 4. I'm wondering could she be an internal layer? Any one have any ideas or do I just need to be patient?
