Hi all. My wife and I started a backyard flock a couple years ago. I always considered White Leghorns to be a sturdy breed but out of the few leghorns we've had, they've all gotten bumblefoot, none of the other breeds have gotten it living in the same surroundings. When I was a kid we had leghorns and their feet and legs were strong, these that we bought at a feed store have frail little feet. My question for anyone who knows, Have they bred down Leghorns, did I buy a mixed breed or was it just bad luck?
