Okay, a little background here
A couple years ago I purchased a pair of egg-eaters. They were relatively new to the world which meant they either had to eat finch eggs (not easy to get your hands on) or be tube fed. The seller was tube feeding them. I had sporadic access to finch eggs and I have tube fed before so I felt comfortable taking them on.
Everything with them has been going well until recently. Over the last couple months I have begun to notice kinks popping up on them. And as the kinks have been popping up the locomotion on the animals has begun to deteriorate. Here are a couple vids from last night (please excuse the manic giggles of my 5 year old in the background), this is the female, she is the least impaired of the pair:
