Personally, I think the reason some don't like Leghorns is that they aren't the appropriate bird for their setup. If one free ranges, wants lots of eggs, and needs a hardy rather than fancy bird, they fit the bill completely. If one keeps their birds in a run, or wants DP hens, they may well be subpar in performance and even end up picking on other hens. Of course, there are lemons, but not many.I would love to know whats wrong about them so I could be prepared,
