I posted a thread today about a hen of ours acting drunk. When I was checking her over I noticed that her crop was empty and that alarmed me. So I got her some eggs and feed, she ate 4 1/2 eggs and some feed through the day today. It was the beginning of the day so she may not have had time to eat much when I got to her. That got me to checking everyone's crop this evening. All of them had full crops, as they always do when I check, but they are all really boney. They were hatched at the beginning of March, so they are right at 6 months old. They are all dual purpose breeds so I would think they should have some meat on them. Their breastbones are sticking out and I can't really feel much meat on them at all. They are free range and have access to 2 acres plus I keep a feeder full of feed at all times. We killed 2 buff roosters when they were right at 5 months old. When they were fully dressed with no bones they gave us about 2 pounds of meat. Would that be underweight? What should I be doing extra?
