we have two polish hens that we bought at an auction a couple of weeks ago, after we got home we noticed the top part of the beak curved down over the bottom one,they dont have any trouble eating as long as there is lots of food in the feeder. we were wondering if anyone know if we should trim their beaks or is this how their beaks are suppose to be. And if they do need to be trimmed....how would we go about doing so?....dremel tool? Peddi Paw? Clippers?...etc.
