Just a normal devilled eggs recipe - but the eggs are reassembled to look like chickens with olive slices for eyes and small bits of capsicum or carrot for noses.
For these, you want the yolk to be positioned as much in the centre as possible. Thats why there's the stirring in the early part of the cooking to keep the eggs moving so the yolk (hopefully) won't settle on one side of the egg.
I tried with one egg first just to get a sense of how this would work. The tricky bit is the boiling and cutting; thats all you really need to test.
