One of my 17 month old hens has a cracked beak. I noticed it today because she wasn't talking grapes from my hand, or picking them up from the ground. She is usually the first for any treat, and usually very excited around treats. I picked her up and while looking her over noticed a crack about 1/4 inch from the end of her beak, about half way across. I think she is eating , her crop wasn't completely empty (430 in the afternoon ). Can I fix it somehow, maybe super glue? I can tell it is bothering her, she is subdued, not her normal self. Any advice is welcome. Thanks.
