My protein is quite low in the feed. I don't really monitor protein I add to be honest. They get a lot of the organs as I have mentioned. They get any cooked meat that is not OK to give to dogs (ie: chicken bone in, turkey bone in etc.) dogs get the ham and steak bones. That and all the protein they get on range from field mice and bugs. Crickets: I wouldn't worry. If they don't get them right away, they'll get them later. They can run, but they can't hide Well I guess they CAN hide, but they will be found eventually. Crickets are a favourite. We have an abundance of them naturally in the spring. Supposedly they are mating in the fall, but I don't hear them at all now as I did in April and May.
