I don't believe they're THAT feathery, especially compared to Pekins. My Pekins look like they're wearing mops on their feet. It's cute, but it adds a lot of maintenance.I'm not sure... we have them in a dirt run (which we may or may not choose to add material too later). It flood's where we are sometimes but i'm not sure how bad it got at the chicken area since we didny have chickens last yr so I didnt pay much attention to any water over that corner of the yard.
Im kind of assuming they'll be fine with feathery feet anyway since the breeder I got them from has dirt practically everywhere and her chickens are always healthy. Note: she's a friend, so i guess I have more insight into their care from our convos?
Dirt can get pretty gross on its own, and if it floods, you start running the risk of coccidiosis and other problems if the run can't dry out quickly. Are you able to get some wood chips from a local landscaping company? Chickens love kicking around in them, and the poop drops below the large pieces. It does need to be refreshed or topped off here and there.
