Marmoset monkeys proven breeder

1 male 1 female. Proven, bonded breeding pair. Male is 3 years old and female is 4 years old. The female is currently pregnant. They need to go to a breeder and not a pet home. The male at a young age was bit by a wasp and half of his leg was amputated before I got them. It does not stop him from breeding or getting around at all. They are very close and bonded to each other. Accepting all reasonable offers!
