May I ask: What is meant by a child chicken? Is there a child duck?
I don't know if you are talking about a famous dish in Kaifeng, Henan Province. If it is that is the name of a kind of roast chicken, is the use of hens as raw materials, not open, do not break the belly, chopping off the claws, remove the lower half of the wings of the large bone joints, from the right bladder under the opening of a 5-centimeter-long crescent moon mouth, the fingers to the inward thrust of the three ribs, the forefinger stirred around the viscera round and then take out; and then from the neck back openings, take out the crop, rinsing clean. The two thighs are broken from the root and tied with a rope. Wrap the whole big stuff in thin cloth. Make the chicken become barrel-shaped, and then and make roast chicken almost the same way made, because the body shape like a barrel, so the name of the barrel chicken is also called child chicken. Children's duck and children's chicken is almost the same.
