Occasionally I will see my chickens "yawn." They don't do it regularly, but most of them seem to do it occasionally. Is this normal, or should I be looking for gapeworms? They do get wormed about three times a year with Eprinex. I don't have enough hands to hold chicken, open mouth, and look down throat with flashlight held between my teeth, but I will try again if ya'll think this could be gapeworm. Otherwise, they are well-fleshed and eating well. Poop looks normal. Egg laying is normal. They free range and so eat lots of bugs as well as layer crumbles, scratch (in moderation), BOSS, and treats.
