Any way to help my finch's beak grow back?
Hi everyone I recently got a new male zebra finch from my local pet store and the poor little guy has a cut on the left side of his beak and it seems like some of his beak eroded away on the sides as well (like the side of his mouth). I didn't realize that he had this issue until after I purchased him (the cage was high up and I'm short so) I knew that he was missing some feathers from other finches bullying him because the cage was overcrowded but I wasn't expecting the beak thing. He doesn't seem to be in pain and is a pretty happy and chill little guy he loves his temporary cage (I have him isolated from my other birds bc he's new and because I want him to be healed up before I introduce him). I can post a picture of him later when I get a higher quality pic of him. Anyways I'm giving him egg food, dried greens, grit, and Volkman Finch seed mix currently. I also gave him a mineral block and a cuttlebone and I wanted to know if all this is enough or if I need to give him more. I've owned zebra finches for over ten years now but this is the first time I've had to deal with a beak injury so I wanted to make sure that I'm feeding him properly
