The eggs are okay to eat. are there any feathers laying about in the coop? You may have a feather eater in your flock. Also how much space per hen do you have? They could b getting board.
we have 7 chickens in a 10'x7' coop...so I don't think they are over crowed. I do see loose feathers in the coop and hen house. I will have to keep on eye out and see if she is picking them out herself. Thanks for the help.
