I am brand spanking new to chickens, so please be a tad patient with me! I have three hens.......all meat birds. Two of them are only about 6 months old and haven't started laying yet. But they have always had a good chicken feed....I switched them onto the laying stuff a few months back. Anyway, the third hen I recently got. She ate whatever she could find, mostly horse grain as she lived in a stable. My kids have found a few eggs she has laid, but they just don't look right to me. I am 99% positive these eggs came from her and not my two young ones. The eggs are not smooth, they are kinda lumpy looking. It looks like there is extra shell "deposits" on them. I hadn't cracked any open because I was scared to try to cook them. This morning, I decided to crack one open and feed it to the cat.....and the sucker had THREE yolks in it! I know that's not normal! Would it be her previous bad diet that would cause this? I am scared to eat the eggs, honestly, but the kids can't wait. So how can I tell if an egg is good or bad? Thanks for the advice!!!!
