If they’re over 4 months old then it’s pretty safe to say they are hens, if under 4 months they could be either. I got my 3 khakis at almost 3 months of age and they all looks the same, brown all over. What turned out to be 2 drakes started getting darker heads before their bodies lightened up...
They are good guards, but our polish rooster is actually the watchdog of the entire flock. He alerts everyone when a hawk is in the area and does his best to make sure everyone gets into cover. And with that said. Our alpha pair of runner ducks is the first to charge our dogs if they come...
I have unsexed ducklings, they are fawn and white runners as well as the Cayuga/Runner mix. I’m in Citra. I’m facing the same problem, the Cayuga drake is the only one I have that doesn’t have a mate.
We have our ducks and chickens together and they do well as long as everyone knows their place in the pecking order. The ducks can be bullies at times so just watch them. And yes ducks are messy, the more water they have to play in the bigger the mess. I have a small kiddie pool, about 3 feet...
I’ve been trying to get a good picture of it but I’d have better luck catching water with a net. It appears to have the same coloring as Cayuga ducklings, maybe a bit more white running down towards the belly, ands stands like a runner.
