I get the impression that's for a fully grown chicken sold for meat. I have no idea how big those chickens are. In North America live chickens sell for between 30 and 50 cents a pound. The chickens in the video look like small roasters, definitely under 10 pounds.

For example, in the US, only about 25% of the cost of bread is for the bread itself (wheat, baking, etc). IIRC, in egypt, about 50% of the retail price of bread is materials/production. Thus bread there costs 1/2 what it costs in the US. But egypt is an outlier in agriculture with an extremely high wheat yields for a nation at their economic situation. Probably due to the fertility of the nile.
