Hi! I have a blue copper maran...she's over a year old... that has been having trouble walking for a couple days. I did check her out when I first noticed it but couldn't find anything wrong. She is eating and drinking well. I checked again today and she has, I believe lost a toe nail and the end of her toe is like a bulb on it. I have attached a photo. I sprayed some veterycin on it but not sure what else to do. Any suggestions? Thank you
