"Where are the hens, by the river or by the tree?"
Translation:Hol vannak a tyúkok, a folyónál vagy a fánál?
Yes, agreed. But in everyday English, chicken is also mostly found on your plate, not wandering outside.
Anyway, in Hungarian, "tyúk" is not just a female chicken, it is a mature, adult, female chicken. The word that matches the English "chicken" the most is "csirke".
You can make "csirkeleves", chicken soup, and you can make "tyúkhúsleves", "hen-meat-soup". This latter one is decidedly made from a fully grown female chicken.
But "csirke" is just "chicken", in everyday Hungarian.
