I have started breeding and intend to replace less than stellar producers with girls from a mom that consistently produces larger litters. Has anyone here kept records of average litter sizes over an extended period and then kept females from those with larger litters to see just how heritable the trait of having large litters is? So far I've had one girl drop 6, one drop 7 and one drop 11 (to include one stillborn). I have three more girls that should be dropping litters in a couple of weeks and am hoping to get at least 10 from them but I'll have to wait and see. Thanks in advance for any help figuring this out!
