I Have two 9 week old chicks that just about 2 weeks ago suddenly got crooked beaks. we diagnosed it as a deficiency in there food and the beak stopped progressing, so there pretty much ok now and are eating just fine, but I don't like how it looks and was wondering if I could put it back some how. it's not very severe and I read that some people rub Penetran+Plus around the beak and it sets back. I'm thinking of using it but I don't want to accidentally kill her with the Penetran by trying to help her. I'm asking if anyone has ever had a bad experience with Penetran+Plus and if it will work in a older bird (not a chick but not laying yet). I'm calling it Penetran+Plus but I think Penetran is the same thing, Thank You!
