We have 3 chickens. Bertha is a Red Sex Link. I have been getting 3 eggs regularly for several weeks. They are young and just started laying at the end of July. Sunday I got 3 regular eggs. Sunday afternoon the chickens are out in the yard and Bertha is behaving strange, not running around, not coming to us expecting treats. Later, she was pretty much hiding under the chair, half sleeping, breathing normally but her tail was up strangely. My husband went out a bit later and she had just laid some soft shelled egg, and one of the other girls had just discovered it and consumed it. Bertha was tired, and her comb was not as bright red as usual (but still red). This morning, I went to let them out of the coop and into the pen and Bertha and CeCe did not come out, I opened up the door and there was CeCe eating another soft shelled egg in the center of the coop, Bertha was in the nesting box and then they both came out. I got two regular eggs. Bertha acted fine until again this evening, and she is acting just like last night - hiding, tail up, half asleep, etc. I am keeping an eye on her to see if another soft shelled thing comes out. Have you heard of a chicken trying to produce too many eggs? And any ideas what is causing this and can it be fixed?
