It's so exciting to have our hens starting to lay eggs! We have 10 Cuckoo Marans hens who lay lovely dark brown shelled eggs. Here are some of the eggs from the past few days. It's a riot to see some of their first eggs as their bodies figure out how things are supposed to work.
Yesterday, I was surprised to find the little yolk-less egg right in the middle of the chicken yard! (The small egg in the center.) Some people call small eggs like this wind eggs-- but I don't think that is the correct term. They're really just yolk-less. According to Wikipedia, yolk-less eggs are usually formed from a bit of tissue that is sloughed off the ovary or oviduct. The tissue stimulates the secreting glands of the oviduct and a yolk-less egg results.
Wind Eggs on the other hand, are eggs that don't have a shell -- just the membrane that surrounds the white and yolk. We actually had one of those in the nest box yesterday, but I didn't get a photo. It was a regular sized egg, but instead of having a hard shell, it had a very squishy thin shell.
Usually wind eggs get broken before they're found since they're so delicate, but Flopsy (one of the Cuckoo Marans hens) was just leaving the nest box when I found her shell-less egg. Sometimes hens who are lacking in calcium lay shell-less eggs, so I added a bit of calcium to the feed. But more than likely, Flopsy's egg mechanism is still working the kinks out.
Eggs make me happy... *grin*
