I am hoping someone here can offer some advice or help regarding an ongoing issue with my poor English budgie, Pip. He is almost 3 years old now and this issue started last year.
Since June 2019 we have been struggling with feather loss. I have taken him to the vet multiple times and we have tried antibiotics, anti-inflammatories (twice) and antihistamines (to rule out behavioural issues) and ivermectin for parasites (though there were none under the microscope). I just finished the second round of antibiotics/anti-inflammatories and he does have some feather growth coming back. The next stem would be more extensive testing of the feather follicles and a blood test.
He seems very irritated and "screams" while preening and when he is trying to rest, he will suddenly start "screaming" at his feathers as if something is biting him. He will look around his body and bite at his feathers but he does not pluck them from my observations. The feathers seem to just fall out and they seem to stay in pin feather form for a long time. Some are even curled a bit. There is always a pile of feathers at the bottom of his cage as if he is constantly moulting.
This most recent round of antibiotics seems to have been working and he wasn't screaming at himself and he looked more comfortable. That is until I let him have a bath. After that, he has been irritated again though some of the pinfeathers released and formed into normal feathers. Could he be allergic to water? Something in the water? I give my birds RO water to drink but regular tap water to bathe in. I will call my vet to discuss this as well.
Below are the images of his feather loss progression.
After this image he was the most bald, his legs, chest, bum and neck. I didn't get pictures
This is after the most recent antibiotic round.
I know rope perches are bad but he falls off most perches very easily and can't catch himself. He doesn't chew it and it offers him some grip. He injured his leg 2 years ago and doesn't have full gripping strength in it. He has many other natural perches in his cage like a cork platform and branches.
