Male / Female pair Marmosets

3 & 4 year old common marmosets. Have never been housed to breed until now. Female hasn't been bred as of date. Both have been "pets" & use to wearing diapers, but the past month they have been housed in an outdoor enclosure, no diapering. They are handled daily. Do have to warm up to new faces but are very sweet. We are in Poynor tx. (East texas) can meet within an hour or so.
