What is on the side of her beak?
Can someone out there please help me?
For the last week, I've noticed what looks like a pit or small gap on the side of my bird CJs beak. I looked at it when I got home and now it looks like something is broke off in it or it may be a piece of pellet stuck in it?
This is the best picture I could get.
She has a broken femur right now and has been really struggling to get around her cage. I removed perches but she will not sit on the bottom so I had to keep one so she could get to food and water.
Could she be rubbing it and maybe that's why the hole is happening? I was just at the vet two weeks ago and it was definitely not like that. I have another vet appt on the 5th but I wanted to get some advice if this needs to be looked at sooner.
Please help.
