I heard this from a lot of people, but I have to say, my experience doesn't support this. All my snakes are on ASFs. I had my first clutch this year and I have a hatchling that was hatched on 7/31 and UNTIL TODAY is still being assist fed. He struck and coiled an ASF on his own on the first week of November but hasn't done it ever since.
So, that theory about ASF providing better feeding response... meh. Not true in my case. My bp's are eating like everybody else's bp's. Sometimes they eat, sometimes they don't.
And I sold my extra hatchling just fine too.
And I bought 2 hatchlings that were eating regular rats, switched over to ASFs without a problem.
So yeah, I have a different take on this.
Facts are:
- OP has 4 snakes - babies from what I understand.
- Getting a mice colony is not going to last him for the long term - they will eventually need to get on rats before a year is up (unless he decides to feed mutliple mice when the snakes get to be adults).
- Starting a rat colony is not going to be very good for 4 small snakes - they'll outgrow the snakes easily. So, unless you plan on freezing the rats when they get to a certain size, this is going to be difficult to cycle.
- ASFs are the better solution - they grow slow and they won't outgrow the snakes.
Worry about breeding later. If you need to switch them to rats to sell, you can do so then.
