I just got these chickens almost 2 weeks ago. They are 9 months old & should all be hens. They are a Barred Plymouth Rock, a Rhode Island Red, and a Black Australorp. The guy I got them from had gotten them as chicks from a hatchery. They came to him w/ their beaks trimmed (don't know if there is another term for it - butchered maybe ). I wish they had full, natural beaks, but they don't. This is my first time having chickens, so it's all a learning experience. I figured if they're 9 months old, they must be able to eat otherwise they wouldn't be alive. I try to watch them when they eat, and it does seem like they don't get food w/ every peck. I feed them layer pellets & a little mixed grain stuff I made up myself (corn, oats, wheat, millet, quinoa, black oil sunflower seeds) On two of them (the RIR & the BA) the lower beak is much longer than the upper beak. The guy said that if they have access to bricks or the like, that they would grind down their lower beaks to meet w/ the upper beak. I'm hoping that this is the case. The BR's lower beak is already pretty even w/ the upper beak, so I'm hoping that this is true. Anyone know if they will self-maintain their beaks? Here are some pics.
