Mine are getting more and more spoiled and I can't seem to stop myself from giving them stuff. Every 2-3 days they get a can of tuna. I need to get more yogurt but I give them that every 2-3 days offset with the tuna. Every day they get swiss chard, beets, lettuce from the garden.
They have gotten accustomed to this and we hear about it if we forget them. 4 little demanding beasts. But they are adorable.
*EDIT* Think it's worth doing though. The eggs are all big and beautiful on the inside. 3 eggs a day from 4 hens ( 2 bantams ). The birds themselves just look great. I don't know anything about show quality but feathers have a nice gloss and they seem very happy.
