My cockatiel has recently been dropping lots of feathers. More than usual. I don’t know if this is molting or maybe he’s bored and preening himself too much? I can’t get him to play with toys and he’s on a seed diet. (I’ve tried so much to get him to eat pellets and he won’t. I don’t know how to get him to eat them and if anyone has advice on getting cockatiels to eat pellets please let me know!) he seems perfectly fine personality wise, he doesn’t seem stressed he’s just dropping a lot of feathers. Is this something I’d need to take him to the vet for? I’ve added some photos of the feathers he’s dropped and photos of him. Thank you!
