Dahlia went in with Ari on 10/2, which puts her at March 1st - April 4 for an Ari-sire, and then April 5-26 for a Richie sire.
Madeline had a quick fling with Richie on November 1st, then moved in with him on the 6th, which gives her a window of March 31 - April 26.
Anna was last into the shag shack, so her window is April 5-26 for a Richie-sire kidding.
