What are the best bins to use for a rack I am designing. I am wanting to house breeders, a place to hold the babies and the mom, I am also going to want to have holding bins as well. I am looking for the best bins to use and maybe a number of each in a good ratio.

I have 30 snakes and want to keep them all fed. I also have a deep freeze to store f/t. How many rats will I need to produce to keep up does anyone know.

Help with this would be much appreciated. Any pictures are of help too.

I am trying to produce the MOST efficient and best rack there is.

Also another question: Can you and does anyone keep there rats on recycled newspaper that is shredded??
