Thank you guys soooo much! I can't even explain how worried I was, it was making me so emotionally stressed I was feeling it physically, I felt like I was going to vomit. Was awful, the rest of the day he was back to his normal self, playing, chewing, scritches, coming when called & wanted to be on me all day like usual. I feel so very thankful!
Monica, your post is interesting & informative, makes me worried again.. it couldn't hurt to have his blood checked & I still really want a DNA. Guess I could do both at the same time. Really wish the vet could've DNA when he had his 2 blood feathers removed, they had blood & fresh feathers, but they couldn't find thier kit to do it, they said they did a DNA on a macaw a week prior & someone miss placed it. So, maybe I'll setup an appointment soon for blood work just to be safe & DNA because I really am starting to think Hercules is female. He's pretty quiet for the most part (as long as I am in sight) be nice to know for sure of his sex, so when I get another cockatiel in the future, I want the same sex, no mating or babies.
Thanks again you guys! I knew this was the place for answers. I hope you all have a fantastic feathery day & I will continue to keep you guys updated on Hercules progress!
God Bless!!!
