My anaconda has been feeding great on live chicks but I can't get him over to rats/mice. I would like some specific ways that have worked for some of you. I've tried these with no go...

Letting a rat co-habitate with some live chicks (supervised of course)

Rubbing a frozen thawed chick on a rat (live/dead)

Dunking a rat in a ducks dirty water

I've tried this on different sizes of rats too.....

Thanks
