I am breeding three W.C . Y. Bellies this season. One is a 2000 gram female who I purchased after she laid last spring. I fasted her for 3 months after I got her. I offered her rats and she is now one of my best feeders. She has been breeding with my new morph(got to get that combo) and 2 different Y.B's. She hasn't taken yet but looks to be developing.
The other two were brought into my collection as 900-1000-gramers last spring. They took a while to get feeding. When the hit the 1250 gram mark, and their weight looked good, I moved them to my breeding room.
I have only been bred by the 2 male offspring of the new morph. Hatched September 24th 2007 they are around 600-700 grams and are flat out studs -- just like daddy!!!
I must say that I got these snakes because the were Y. B's (not normals) and to gain some experiance as a new breeder. I have a lot of captive hatched in my collection, but will be not likely to get any more W.C. -- unless they were EXCEPTIONAL and the price was right.
