Well like I say some people might think differently as you obviously do. I couldn't agree more that they'd pick on Anything in the wild but I just don't feed mymgirks meat:)
I don't know if this aids anyone but my hens eat whatever there given.. I don't like to see any food go to waste and I like to save a few quid along the way,
Stale bread,
Veg peelings,
Old fruit,
Duckweed,
Weeds/grass cuttings,
Leftover food,
I feed all of my girls on this kinda stuff...
