Hello yall, I wouldn't say i am new to this forum, i have been lurking as a guest for the past year, now i am getting into breeding and i am having trouble determining a complete setup with tubs and housing.

currently i have a 6 bay rack with mixing tubs, will be adding another 5 bay by Wednesday. i have 3.12 rats, every 4 females were from different private breeders, same with each male (no chance of inbreeding).

i have read the great post with the colorful charts and time lines. i get pairing one each week to feed off ~10 consistently... well i need to feed off 24 currently....

where i am lost is how to keep females that are not being paired, raising, rearing organization and males not to be mixed up so that i may not in breed/over work. i understand that i know currently which male is which is not important due to being from different breeders.

by the master chart, i should be breeding at the minimum... 3 females a week. then after two, remove the male and keep the females alone... i have just experienced 3 females fight over newborns sooo i know i will need two birthing tubs or just removing the male...

for a colony of 39 rats plus rearing all the way to jumbo (i have some retics not on rabbits yet), how many tubs would i need to do this? i understand that roughly sizing goes by weeks, and smaller sizes will free up quicker. but what are some simple ways to keep organized and pro tips to help me along my way. currently have a couple new born litters (this past week)

thanks for the help,

Zack
