Just look at BRB's..
They have anywhere from 10-30 babies and lets say one did have 30 babies. If you sold all of them for $150 which is average online thats $4,500.
I am in no way wanting to get rich off this or even gain a nice car and house i just want enough money to keep food in my house and have a little cash for other things and if my math is right this can be done with a little hard work, time and dedication.
Also i will be breeding rats/mice so its cheaper and me and my friend are doing this together so thats two incomes and we will also be roomates spliting half on rent so with both of us working and selling snakes i think this would be nice but i guess theres only one way to find out :P
