okay so the first time was strange enough, but the second time I started to worry, but now it's happened again--one of our chickens has laid a completely shell-less egg for the 3rd time in about 2 weeks. In between there have been a few normal eggs. She's the only one laying right now since our other laying hen is broody and the others are too young. Can anyone tell me what's going on? I had to buy eggs at Costco yesterday--yikes!
