Had them around, and just figured I'd try it out one day, see how she acted. My Hog Island girl will eat them too, but the rest are still a tad small for those big ol legs.
I do it once in a while, just to vary her diet a little. I do prefer whole chicken for the more complete nutrition package, but they aren't always available in the right size.
I believe in a varied diet though. Never had a problem with them taking to one item and refusing others either. Although I have experienced that birds seem to wake a problem feeder up. For some reason, even a problem feeder seems to think birds are the frosting on the cake.
