This post reminded of before we moved onto our boat, when we lived in an old irish cottage. We kept chickens and rabbits for food and as avid fishermen we always had to "breed" our own maggots for bait as there were no shops for miles around.
Needless to say, our hens had their share of these maggots also and would sit on the highest rail of our fence every morning where the bucket of maggots where kept, waiting til i came out and took the lid off. Once they saw the lid was off, it was bedlam almost to the point of fighting. They loved those maggots..
Hens are a funny bird too, great entertainment at times.
