searching for rats

Not sure if this is the right place to post this as I'm new to the site and guessing but my fiancé and I are looking to expand our rat clan. We currently have three boys and would like to add a couple girls to the group but will gladly take more boys. If any one has or knows of any needing a loving home in Upstate New York please let me know. We have one Dumbo cross, one fancy and one Dumbo (possible Dumbo cross). They are 5 months, 3 months and 1 month old so we would prefer that age range if at all possible.
