It looks like I should have followed your lead and started a new game when I opened and saw only one male but alas I am to far into it now.
My update is now the next was a male but now followed by two more females. I guess this is going to be tough to keep alive so will have to play it only when I'm sitting right in front of the computer and pray for the canoe event when another male shows up to breed my ladies with so brother is not mating with his sisters. Yuck, no mating this little guy unless the canoe even happens soon.
