What are your breeding ratio? I read some labs would have 1:1 1 male to 1 female, 1:3 1 male to 3 female. While some breeders would have 3-5 females and I read on forum some pinkie "factory" would have upwards of 15 females to 1 male. What is the most you have heard work? I can not imagine 1 male to 30 females, it would be non stop work for the male? Not to mention the size of the tank/bin.
