The hens have bare backs due to treading by the roos, most likely.

Chickens love eggs and it is a very bad habit which can be hard to break, they will fight over the eggs. Try and correct your management by gathering eggs mor often, put some golf balls in the nests, darken nest boxes.

If you have a hen (or rooster) who is a habitual egg eater and you can't cure them of it, best to eat the hen. I had a guinea that ate eggs. That guinea tasted really good.

I think that our problem was that when our hens layed in their laying boxes there wasnt enought straw in with them thus causing the agg to sometimes crack and that caused them to eat them. Does this make since?

Thank you all so much for the help!
