So it's in the teens with a foot of snow, and I walk outside to check on my chickens. I open the coop and the big bag of happy hen treat mealworms is tore in half and empty. It's was a bit more than half full and I'm worried that they will get sick because of how many they ate. They have food and water in the coop along with a heat lamp ( they have been staying in the coop for a while because of the weather). My chickens are less than a year old and most are bantams. Will they be ok? Are that many treats going to hurt them?
