How funny! I'm not surprised by the veggies. They do like that stuff. I mean birds generally. I had a friend in Milan who had a basil plant growing on her kitchen table, which was near the French doors. She kept the doors open in warm weather.
And was puzzled because it seemed something was nibbling on the leaves. Then early one morning she went to the kitchen and discovered a couple of sparrows chowing down.
But the chicken seems a bit... cannibalistic.
Aren't ibis water birds? They may eat fish naturally.
