This seems odd to me but I'm still fairly new at the chicken thing so maybe someone can help clue me in... I went out this morning to check on my chickens and in one of the nest boxes was a very small dead mouse. Would one of the chickens killed it? I've never noticed a mouse problem since I've had the chickens. I have 7 chickens total and most are almost 1 year of age. I just found this odd and thought I'd ask an expert (or several) .
