I haven't seen an answer this specific especially when it relates to the males trying the drown the ducklings as my pekin and rouen tried a couple times last month when momma runner and the kids made their escapes for the pond. But I went away for a week and now the ducks seem so HUGE. They're a month old now and even the littlest one is almost as big as the runner. The temporary duck pen in the garage is a disaster with the poop (DH is aghast at the mess, he's the one that looked after them while I was gone) and DH would love to have them outside. So what are the chances of the daddy ducks still trying to drown their kids? Momma runner is no match for the bigger guys.
