So the 3 girls are coming up on 5 months old. In the last week, the pool has been interesting - usually it is Blue on Cadbury, but the other day it was Blue on top of Ally and then Cadbury climbed on top of the pile and I had a 3 ring duck circus. I assume this is kind of mating behavior, but somebody hasn't figured out that she's well, a she and won't get anywhere with climbing on top of somebody else and riding them around the pool. As long as I see the underwater duck being able to poke her bill out for air, I don't intervene, but when I haven't, I go push Blue off who ever she's riding. Will they eventually figure out they are all girls and this is pointless or is this some dominance thing or something else or what?
