Ok, I will bring them up some, but not too much. I don't want to be charging an arm and leg like the pet store. I know I would love it if I could buy heathy, properly sized rodents at a fraction of what I buy them for now so that is something I would like to give to people in the area. Rats that are free from wounds, disease, infections (I have gotten rats like this as feeders.) and don't cost you so much. Maybe something like this?

Mouse:

Pinkies - 0.25
Fuzzies - 0.50
Hoppers - 0.75
Weans - $1.00
Adults - $1.50

Rats:

Pinkies - $1.00
Fuzzies - $1.50 (2 weeks old)
Weans - $1.75 (3 weeks old)
Smalls - $2.00 (up to 100g)
Mediums - $3.00 (up to 200g)
Large - $4.00 (250g +)
Jumbo - $5.00 (retired breeders)

What about getting the feeders to the customer? Deliver them? Have them come to you?
