The most important thing is to start off with a little gas to put them to sleep first, then flood the chamber to kill them. if they are awake when you flood the chamber with gas it won't be painless.

I ended up just feeding it to them and watching very closely, imma get some dry ice and use a bucket to do it and see about doing like 10 and freezing them

Re: Pre killed
I went online and got plans for a small and simple CO2 chamber. Works quite well.
