Hi all. I have had my 3 backyard hens for 3 years now, and they are nearly done their molt. They haven't laid in 2 months, which I attributed to the molt. However, when cleaning the coop and run on the weekend, I palpated their breast tissue, and could feel the keel bone, and the breast is thinner than I would like. I feed Dumor laying feed (free feeding in a step on door feeder), fresh greens, veggie peelings, ground egg shells and I have upped their scratch to a big scoop of about 4c daily. Today I added rolled oats. What am I missing?
