Last year I had two bee hives in which the bees disappeared, they had done well in previous years. I know that there are many possible reasons for their disappearance, however I had made one new change. I bought 9 chickens which I allowed to free range by the hives. I was out there many times with them and never noticed the chickens bothering the bee but this year since I've put in 3 new hives, I'm wondering if perhaps the chickens could have eaten the bees. Does anyone have an answer?
