Just adopted three hens from the Humane Society and one that has it's beak tip cut off. Why would someone do this? Her lower beak is a smidge longer than the top so she has a problem eating layer pellets so changed all my chickens to crumbles. Didn't realize until I was watching her try to eat the pellets that she was having real difficulty doing it. So, immediately bought a 50# bag of the crumbles for all of them. She ate and ate and ate. Why would someone do that?
