Trevor is not going to be producing this year. :-(
I guess I will just have to look around.
I really am sorry about this. I wish I was still working with them. Right now I am without House Snakes completely. But, I do work for a reptile shop and I will let you know of any House Snake breeders I know.
http://mfezi.com almost always has House Snakes for sale. I might be picking some up from them.
There are also some new morphs in House Snakes. A hypo has been proven to be a genetic recessive trait. I have seen them and they are VERY cool.
There are also Anerys now. I haven't seen these, but I am very much looking forward to seeing/getting some.
This is a great question. I don't think there's much data out there concerning sperm retention in house snakes. I'm operating under the assumption that fertility for them will follow the same very general guidelines as other colubrids, and that a first-time breeder can't retain a million ready sperm for years. I'd expect two good breeding sessions to produce one good clutch and maybe a second. The possiblity of a third or even a fourth clutch reinforces my resolve to make sure that she far exceeds MINIMUM breeding size when I breed her. I think you'll find that the extreme multi-clutching stories are the result of cohabitation by people who are more accustomed to keeping North American colubrids.
I have a bit of input on this.
I had 3 of my females double clutch from one breeding, and I got mostly fertile eggs. In fact, the snakes that you have Dean, are from those clutches.
One of those 3 females actually laid a 3rd clutch without ever being introduced to a male again, but all of the eggs were infertile.
The best way to go about getting lots of eggs, healthy babies, and keeping your females healthy is to do what Dean had said. Wait until your females are over 300g. If you do that, your females will pretty much produce clutch after clutch, year round, and still maintain good weight and health.
Everything I have read about pushing a female to soon has said that she will give you a couple of clutches and then refuse food until she dies. So it's worth waiting a couple of years.
