Hi,

Thank you for all of the great help so far. I'm newer to breeding rats for feeders and I just got my 2 racks setup about a month ago. I have a whole colony of 4 females that are all pregnant right now and I had one just drop a litter. About how long after she has her litter should I put the male back in with the females to get her pregnant again? She had a litter of 13 babies which I'm assuming is a decent amount. I've heard putting males back in there right after can decrease their liter sizes which I for sure don't want. Appreciate the help!
