In fact, when Europeans first entered America, they came to a strange country, and they were very unfamiliar with all of them. They had no relatives or money, so basically they could not even guarantee food and clothing. Especially when winter comes, the climate becomes very cold and harsh, and many Europeans will freeze to death or starve to death alive at this time.
At that time, the Indians in America kindly sent these Europeans food, clothes and some daily necessities. Indians also used the turkeys they hunted to entertain these Europeans. Later, in order to thank these Indians for their enthusiastic help, and to make future generations remember this kindness, foreign countries took Thursday around November as Thanksgiving Day to express their gratitude. On this day, foreign families will get together and eat turkey to celebrate.
Moreover, the turkey was actually domesticated at that time. Europeans liked to eat big geese before, but after eating the turkey, they found that the protein of the turkey was rich and the taste was much better than that of the ordinary big geese. So many families began to eat turkey at that time. In fact, not only do we eat turkey on Thanksgiving, but some families also eat turkey at Christmas or other festive festivals.
Turkey looks bigger than ordinary chicken, and it is more widely used. The key point is that its meat is still juicy. If you use ordinary roast chicken, it is too small for a family to eat at all. It may take five or six roast chickens to eat at Thanksgiving. But if you choose a turkey, a medium-sized turkey can meet the needs of a family, and it is more suitable for foreigners' tastes.
