I've got six hens; 3 Sexlinks, 1 Mottled Java, a mostly-Wyandotte and a Whoknowswhat. I have them in a fenced area with a good coop. Until fall they all laid every day, with nice looking eggs. They are well fed with Layena, oyster sell, poultry booster, and diatomaceous earth. I make sure they have plenty of fresh water, I keep the straw in their coop changed frequently and they have a light for heat/longer day during the winter (wasn't a problem last year, so...). I began to have less eggs every day. At first I blamed it on seasons changing but then I was finding sticky, gooey broken egg mess in the communal nest pretty often. One of my Sexlink's egg's had started being really thin-shelled so I thought the other hens were breaking them when laying. A couple of weeks ago my husband caught one of the sexlinks in the act of eating an egg. Needless to say I was disgusted and worried that they were all doing it. He sectioned off the coop and the "run" area and put the cannibal hen in it to see if that made a difference. I think it has because I'm getting more eggs. I've gotten a couple of eggs from the jailbird but the one today had a crack in it shaped just like her beak (it had been cut off by the breeder: boo hiss). Is there any hope for her at all or should I just give her the death penalty? Is she doing it because her eggs are so thin? Also, why did the eggs from the Sexlinks go from being a beautiful dark, reddish brown to light brown or tan color? Ok. That's it. Help?
