I'm breeding pinkies (fuzzies to be more specific) for my snakes and I have a few questions:

1. Is it necessary to leave a couple pinkies for the female to raise in order for her to continue breeding?

Since the mice stink so badly, I have to keep them on my back porch, which means when it gets cold out I have to kill all of them. There isn't enough time for me to let the young ones mature and begin producing. So it would give me more work during the summer and make my job more heart-wrenching at the end of fall. I'm not really sure what I should do. I would prefer to take and freeze the whole litter but I don't know if this would stop the females from producing or cause them to kill their litters.

2. I have access to Ether, which I've found is a very humane way to put animals down. Would Ether, which evaporates quickly, remain in the lungs of a dead pinky or fuzzy? If it does remain in the lungs, how harmful would it be to a snake?

3. If Ether is not an option, what would be the most humane way of extermination? I need fuzzies so freezing is not an option.

Any advice would be appreciated. Thank You!
