Hello guys, I am not sure what is happening with my roo but almost every time he bends down to drink water he will keep his head down and starting walking backwards until he finishes swallowing. Then he brings his head up back normally and resumes. I also noticed it when he went to peck at something on the ground. I'm not sure if he's in pain or what the cause is but I started noticing this about a month ago? What can I do? Thank you!
