"Chickens are yellow."

Translation: Kuřata jsou žlutá.

[gSee4]

Why is Slepice jsou žluté wrong

[Nemesis_NaR]

"Slepice" is a "hen" and I don't think "slepice" is a valid translation in this sentence.

[liesvanhoorebeke]

Chicken is very much used as a synonym for hen (a Google image search for "chicken animal" yields almost exclusively adult hens). Kuřata are babies and are called "chicks". So if anything I feel slepice is more accurate than kuřata.

[VladaFu]

That is correct and in other sentences "slepice" is accepted for "chicken" but the meaning of the sentence "are yellow" shows the speaker probably really meant chicks.
