The other day I found an egg in the nest that looked like a hen had pecked a hole in it. No biggie, I thought. It did not penetrate the membrane, looked fine when I cracked it open. So, I used it, no problem. Then yesterday I found another one with a hole in it and what looked like a "wick" sticking out of the hole. Did not eat that one. Then again today another one. Membrane still intact on these two also. All the girls are eating and drinking fine. No one is behaving strange. They have crushed shell available. I did recently change their food. They kept eating all the grower feed I had out for the pullets, so I switched to all flock in two of the three feeders. The third feeder still has layer pellets, their original food. Not sure which hen is laying these eggs. Thoughts anyone?
