I have a barred rock hen who is 2. She and the others have been fine. Suddenly she's laying shelless eggs. I noticed (may be a unrelated) that the red skin is showing more under her wattle around the very top of her head. I noticed her bottom looked a little "different" today, so picked her up. She's not picked up alot so she got frightened and I felt something warm slide down my leg and down into my boot. Ah, of course, another shelless egg. The eggs have been like this since they started laying regular again this spring. I let nature take its course over the winter. Another hen is laying just odd eggs. Shells are okay, but shapes are varying and not typical. Do I have sick chickens? They are very well taken care of without excess.
