I know i've seen this posted on here somewhere before, but I've been unable to find it in a search. I have a hen (not sure which one) that's been laying an egg that appears to be coated with yolk. It's a thin dry layer by the time I get to it, but it's been happening for about a week now. They all appear to be healthy, I haven't noticed an unusual behavior. Just some chapped combs from the cold. My hens just picked up the pace of laying again about two weeks ago, so I don't know if it could be just about getting back into the swing of things or not. Thanks!
