Today while collecting eggs I found these two things in nesting box next to the eggs. The clear one looks to me like a shell-less and yolk-less egg, and the other is a dried up something... maybe a shell-less egg from a few days ago? Last week I suspected that one of my hens was possibly egg bound, but she returned to her normal self after only one day of being under the weather, so I didn't stress it. I gave extra calcium - milk, yogurt, egg shells, and everyone has seemed fine. I'm not sure if what I found today is from today or if I've been missing it. The clear one is about an inch long and 1/2 inch wide, very soft and feels like I could pop it. The other is about two inches long and when I cut it in half it's folded throughout and pretty dried up all the way through, a little egg-white-like stuff oozing. Both have wood shavings and bits of grass stuck to them. Is this familiar to anyone? Should I change or add something to their diet?
