You think everyone is doing great, and suddenly they aren't, that's what happened between Nerd and Beeper. At first they would safely hang out by each other, then Nerd got upset and jealous of the tiny bird who could fly better and faster than he could and was getting daddy's attention. She also would not leave him alone so it became a battle of wills between them even after we knew they weren't safe together. He made it his mission to slowly whittle her down a piece at a time and she always tried to get at the big bird if she could.
We had to keep adjusting our safety protocols so we wouldn't loose her and she tried her best to make it a challenge. I'm glad everyone is ok and you'll have a much better handle on how to do things, it's really hard sometimes.
