I currently have 2 different lines of asfr's

line A is pied (i think they are called)with clean butts and pink ears

line B are pieds with dirty butts and black ears, i also have one gremlin that i got with the second line too

so far line A has had 2 litters each. so between 2 females the litter sizes were 6, 5, 3, and 3 and the pinkies were smaller than line B's pinkies too

Line B i've gotten 3 litters so far from 3 females. 12, 17, and 18. And they were all nice and big pinkies

So my question is: has anyone noticed this big of a difference in their lines of asfs?

i think what i am going to do is make a new group from B to replace A if line A's litter numbers dont improve
