I have 10 hens and they started laying about a month ago. So far they are big, small, rough, smooth abnormally shaped and lots of double yolkers. So far I've been really lucky and they go back in their coop to lay! They free range from dusk till dawn. The last three days we have been getting between 7 to 9 eggs a day! This just seems like a lot to me for only 10 hens??? Also this morning I let them out and collected 5 eggs then while I was doing yard work one of my hens went back into the coop. A little later I went in and there were 2 eggs in the nest she had been in. Is that even possible or did a hen sneak in there that I missed?
