>>I have bred large amounts of rats in the past but I never really worried about the science of it. I mean lets be honest, ya throw em together and they do the rest but I am only going to be breeding enough to feed one snake now so I would like to get them going as fast as possible. So can anyone give me the estimated amount of days for gestation, weaning age of babies, all those things. Thanks for your age.
I often hold off breeding my females til they are 12 wks old. Pet people will wait even longer but I have not seen any detriment with younger. Some will just leave the girls in with dad or another mature male and they breed when they breed. When I have done that I have seen some get bred at 8wks or younger and thought it stunted their growth and made caring for the litter more of a struggle as they were growing and trying to make milk etc.
When I am starting a new group I will take 10-12 wk old girls and often a mature male. If I have time I may add a younger male (age group of the girls), but often they start slower.
Gestation is 21-24days.
I wean mine at 4 wks. Some wean younger but I like my weanlings to be as big as possible and just don't see that if weaned earlier. They end up playing catch up, and sometimes they simply don't thrive.
Mine, by four weeks are half again or double the size of those weaned younger. So, to some extent it will depend on what you need in sizes.
I do also feed off many at 2 weeks as they are 30-40 grams then and mouse size for my ratsnakes. So the remaining pups have loads of milk without overtaxing mom, who is bred back right after kindling.
All that said. Unless you buy an obviously pregnant mom you are going to have a socializing time when the group has to get used to each other before they breed. I never recommend putting adult, large rats together for breeding. Instead I say get smalls or mediums (typically smalls are 4 wks to about 8wks-12wks for mediums and let them grow together. In the long run you will get more rats out of them and you have a time to tame them to trust you.
