CEl45, my girls are 6 months old. As of today, I got 6 eggs, counting the even/ shelless egg where as i had only been getting 3 consistently and many days a fourth. So 5 and six just occurred as of yesterday and today. I don't know enough to have any thoughts on your suggestion of a plug but it makes sense to me.
Junebuggena, I will certainly keep my eye out to see if maybe she is just fussing too much with the straw causing her egg to break, or if she is pecking at it. I have one hen that just doesn't like me and I caught her a couple times pecking an egg as I was checking on the girls and taking an egg out. She used to peck at me every chance she got but has sense started to retaliate in other ways. I am embarrassed to admit that I cannot tell my girls apart. There are 2 that are significantly bigger than the others and it's one of the bigger girls that doesn't like me. But I don't know who lays when me what....
They have had some changes recently and I hate to think I have caused them undue stress leading to a problem. They had been fully free range except at night but wouldn't stay on our property, crossing the road and such so they are locked up more in a pen now.
I have planned to watch the situation, if it occurs again I will evaluate food issues, and entertainment and nesting boxes...I looked into the roll away nesting box, that may be what I try if i continue to find this mess.
I appreciate any thoughts but for now, I suppose I have some really good suggestions to look out for
