Today I was feeding my chickens some sunflower seeds and noticed my rooster seemed to be having a problem picking up the seeds. As I looked more closely at him I saw his upper beak looked as if the top layer had cracked and peeled off, revealing a slightly pink color underneath (like a fingernail bed) and his upper beak is a bit shorter than the lower beak) I am worried that it is painful for him and that it is making it difficult for him to eat? Also what happened and if this is normal of not? Should I take him to the vet to maybe trim the lower beak so they match? This is all new to me and I am worried. Thanks so much for any help or advice.
