In the nursery rhyme how many blackbirds were baked in a pie?

The nursery rhyme Sing a song of sixpence:

Sing a song of sixpence a pocket full of rye,

Four and twenty blackbirds baked in a pie.

When the pie was opened the birds began to sing,

Oh wasn't that a dainty dish to set before the king?

The king was in his counting house counting out his money,

The queen was in the parlour eating bread and honey

The maid was in the garden hanging out the clothes,

When down came a blackbird and pecked off her nose!

The words to this children's action nursery rhyme which is often referred to as blackbirds baked in a pie probably because the image that blackbirds baked in a pie would create in a child's mind . The rye ( a pocketful of rye) was purchased to feed birds. Blackbirds, and other song birds, were actually eaten as a delicacy! However a court jester may well have suggested to the court cook to bake a pie pastry crust and place this over some live blackbirds to surprise and amuse the King! It would not be unreasonable for the blackbirds to look for revenge hence "When down came a blackbird and pecked off her nose!" It is interesting to note that the references to the counting house and eating honey were the common man's perception of what a King and Queen spent their time doing. The nursery rhyme Sing a song of sixpence or blackbirds baked in a pie always end with the tweaking of a child's nose!
