Parakeet has runny poop, clusters around bottom
I’ve had my parakeet for a little over 7 years now. Lately I’ve noticed that his poop has been very runny. Sometimes it clusters around his bottom and gets stuck in his feathers. I try to give him bathes or clean it with a Qtips, but poop gets stuck there by the end of the day.
Once his bottom has been cleaned we noticed that his anus seemed to be swollen. I have kept his diet constant so I’m worried his health may be declining due to old age. I plan on taking him in to his vet asap, but I just wanted a second opinion. He’s prescribed antibiotics before and it seems to help for a little while.
He recovered but we’ve noticed that he has developed spiky feathers above his nose and all around his head, but no where else. We can always tell when something is wrong when he ruffles his feathers and stays fluffy. He’s been sleeping a lot during the day as well so we have been keeping his heater nearby. What else can we do? Is there anything in particular that may be wrong with him? Thank you for your time.
