Hello All, I'm new to the forum but have been following many trends for assistance in my problem. I had a Peacock which we call Pretty boy George fly up on my property 6 years ago. I fed him and built a cage and perches around my property. He has never had a female hen while with me. Never wormed him or given any medications, as I let him roam free except at night I lock him up in his cage for safety. All has been good up to now. I started noticing weakness, holding wings down, acting sleepy all the time and a bit off balance around 7/5/16 and started gaining information at that time through many online forums. I started him first on a wormer/ Safeguard for three days, using a paste, about a thumb nails worth, as I was told from the Southern states feed store clerk to do. Seemed to help for about two days then he went down showing weakness again, so I went to my vet and got some Sulfamethoxazole-TMP Susp (Bactrim) to see if that would work. Gave that to him for 10 days once a day at 6milliliters by mouth once a day. Didn't see any improvement! So, I went back to my vet and got some Metronidazole 250mg/ one tablet twice a day. I also starting syringe feeding a bit as well. To be exact only 1/2 once last night, then this morning 33ml of combination of Kale, blueberries, can cat food. He is to weak to run to far from me, but tries. He is a bit more attentive this morning but picking his food but not actually eating. What am I doing wrong or how quick should I see some results from this medicine? I think he has Blackhead due to his poop is bright yellow with a hint of white paste around the sides. I totally cleaned his pen and also noticed lice or mites on him, so I powdered him with a pesticide. (see less today) He is standing in his water that I have for him to cool off in, due to it's 96 degrees here in Delaware this week. Bad time for my bird to be ill. Any advice would be helpful. Or, just some insight if I'm doing things correct as I have read many pages of different approaches. I feel horrible as I love him dearly and should had educated myself better prior to this situation. He is the only peacock I've ever had and the only one on my property. Please help!
