I decided to try a deep litter system in my breeders loft for the first time. Yesterday I covered the plywood floor with 2in of corn cob bedding. This morning when I went out to check on the birds, I found piles of vomit all over the place. The vomit contained pieces of the litter. One of my best cockbirds still has an extended crop from the night before. I have a few questions. Has anyone had experience with this? Do you think the birds have learned their lesson? Are the birds going to be alright? Is there anything I should/can do?
