right now i have 2 cages setup that are joined together with a tube of hardware cloth so all the rats can interact. i have 2 jumbo females (albino and a white/light beige mixed), and the rest are around 8 weeks old...1 dumbo albino female , 1 light beige male, 1 charcoal male, 1 light beige rex male.

ratio is 3:3 so id like to remove 2 males....but which ones? they are all the same age and from 2 seperate homes. the rex came with the albino dumbo so im not sure if they are siblings or not. he is very friendly and begs to come out of the cage but is he going to be a good breeder?

they have all been together for a week or so. when will i know if they are pregnant or not? im guessing theres no way to tell?


also, i have 1 male and 8 female mice together right now in a 15 gallon long with 2 different hides but they still cram into the same one. when the females are about to pop, should i seperate them? how many mothers could i keep in a 10 gallon tank? 15 gallon long?
