Gld there okay.
My tiels had bad one once blood all over. That thats not case here.

No blood, but a few of them looked a bit dishevelled for a few days... You know, crest messed up, back feathers lifted up etc. I can tell you, they spent two days preening and now they all look OK.
Obviously I couldn't leave them alone so I spent quite a lot of time ambushing them and giving them a "hair" treatment myself lol
No more messy crests!

I agree Tielfan, the speed they build up in just a few metres is amazing, I am aware of how lucky I was that nothing horrible happened.
I have taken steps to ensure that this will never happen again. I thought working nights wouldn't affect them, it obviously does so no more of it. I will try to find a job that allows me to take better care of them when they are out of the cages.
