Hi Michele!!
-- Since he's been courting a hen, has he started singing again or is no sound coming out still?
He was completely mute, not one sound. The hen however was responding with a sound.
Is his hunched, droopy winged posture the only sign indication that he may not be 100%?
Yes, and no sound comes out of him when he tries to sing, everything else seems to be fine.
Or, does he simply perch with no wing movement?
Yes, he doesn't flutter his wings at all - which I've seen one of my other birds do a long time ago when he was in a smaller hospital cage, I upgraded to a bigger one since.
In your situation, it could be the T-Sulfa didn't eradicate all of the coccidiosis or the tetracycline didn't eradicate all of the URI. Or, it could be something else entirely.
His droppings look perfect, there used to be blood, green, and undigested food but that is completely gone, I assume if he still has coccidiosis the problem would persist right?
As for URI, he still couldn't sing and that indicates that the problem isn't solved yet. Aside from the no-sound, hunched back, and droopy wings - there is absolutely no other sign.
So far I didn't use probiotics, I was supposed to add it tomorrow morning. When I treated with T-sulfa I treated all my birds for 5 days and then isolated the sick one and continued treating him for 5 more days. Then when treating tetracycline I used it for 3 days on everyone and then 2 more days for him.
Should I isolate him again and go back to using Tetracycline? Here's the composition of the one I use, it may not be strong enough:
Tetracycline............................................... 3.10 IU
Erythromycin............................................. 3.10 IU
Thiamine hydrochloride (vitamin B1)......... 40 mg
Riboflavine base (vitamin B2)................... 60 mg
Pyridoxine hydrochloride (vitamin B6)....... 60mg
Nicotinamide (vitamin PP)......................... 500 mg
Calcium panthothenate............................ 220 mg
Thank you
so much Michele!!!!
