So this year I have raise Naked Necks, CX and FR's for meat birds. The first two went off with no issues. NN's avg'd 3.8 lbs at 12 weeks. CX avg'd 6.8 lbs at 7/8 weeks. Can say of the two I preferred the NN for flavor and they ate about 25% less food and were far from as messy. But the CX were still good. Just more work. FR's well they will be getting processed in 12 days and from week three on have had huge loses. 65+ birds within a week to 10 day span then one or two every now and then for no reason. Well yesterday I noticed a couple of them had crops the size of softballs. I thought maybe they filled with air or were drinking a lot of water. When I feel them they feel like air or water not much food but they dive into the food bin and eat like crazy. Well now I see about 3 more. Is there anything anyone can point out to what may cause their crops to be that large? Will they shrink or do I just need to start processing birds now which is not in my schedule.
