Can you sell your extras. Seems people in The Great White North are crying for rat breeders. Feed for ASF an rats is cheap. I sell my extra rats (ASF) at $2USD adults, $1.50 juveniles an .50 pinks. For pets I get $10 for ASF an $5-8 on rats. I make a little money, pay for rat supplies an feed my snakes. The most expensive thing I bought for the rats was the vacuum sealer. If I tried harder I would make real money with rats. But I'm small an like it that way. Have something come up, too much work or a long deployment just gas an freeze the colony. Snakes eat well on rodents you know are safe. When you get time start another colony or two.

For gas, in the States, beer brewing shops an paintball shops have the small tanks cheap. I went big, found two large tanks at an auction cheap.

Just do it! Your snakes will be better off.
