Ok so I am literally going to start breeding friday. My friend gave me 31 rats at close to breeding size. I pick up an awesome deal of a pro built rack so I will be bothering for advice. I have read everything written I can find about starting to breed but I am always on the lookout for stuff like how to know when a female is pregnant before its too late. Can you control the species like you can by line breeding snakes. Just things to watch out for....
