I wouldn't think there would be much to a chick, eating wise. I have heard about the ducklings eaten out of the egg, it didn't tickle my fancy too much..LOL..
I would definately wait about a week before trying it, because then at least the yolk would be absorbed.
If you are looking for an economical use for the male chicks, you could look at grinding them up and using them as a protein source.. I personally don't think you'll get much business selling fried day-old chicks..LOL.
But, hey, you could try it and see. I think if it was profitable though, I think all the big commercial hatcheries would have jumped on the opportunity to make a litte $$ off all those unwanted male chicks..
