Hi there! I am new to BYC. Glad to be here. Lately when I crack open eggs from my backyard hens, occasionally I will find yellowish whites, threaded with veins and a chick embryo. Not appetizing. The hens are about 9 months old and this has just started in the last few weeks. The eggs are laid and collected every day. They are stored at room temp for a day or so, then washed and refrigerated. I do have a rooster and one broody hen who is setting (day 21 today!). Any ideas? Thanks!
