Thanks all...the bird cage actually has smaller bars than most even hamster cages...it was used for finches...it's just really tall. I used metal zip ties on any place that could be a method of escape. I will be moving the female out when she's ready to give birth...the grouping is just for now. I only have one snake (for now), so one female is enough for me. The buck actually seems to be taking better care of the pups than the doe so I'm not worried about all that. My snake is still eating rat pups so those will go quick....I have about 15 unused aquariums so extra caging isn't an issue for separating the male and female pups.
As for any unwanted or unused offspring my neighbor has snakes as well and will be taking them =)
Thanks for the reminder on how to "potty train"...definitely going to go that route. Even though they are food I am still treating them like pets...don't want aggressive or unhealthy rats!
Any other tips or tricks are appreciated! <3
