I don't know why but it always happens to me I need adult sized feeders ( asf ) I end up with all the females giving birth and have to wait the month or so for them to wean. with he rats my problem is they grow up faster than I can feed them off. Like right now I got my 2 new bp and only 3 rat pups left thatthey can eat. but I got about 5-8 small rats just abotu the size for my yearlings. lol now when i need those small rats I won't have any .. I guess it a good thing I have the asf for those time and i can feed offthe large rats to my boa or freeze them at right size for later use lol..
