White Backed Mousebirds

We have a trio of White backed mousebirds available. We recently lost our female and have the remaining four year old male and 2 (we believe)two year old females. We're hoping someone out there has an existing group and would like to expand it. We would also be open to trading the two younger birds for a female. All three bred indoors so are relatively calm for mousebirds. Asking $400 plus shipping. We don't use USPS as there is no overnight guarantee from our area.
Prefer text but phone OK.
