I reported the same. it should be accepted :/

I think that is like saying it twice "Where do they they keep the chickens" since "tengono" is "they keep".

I wrote that and got it wrong. I don't know why as loro is they. Can someone explain please and thank you.

Same here, I don't get it.

me too. 5 years later and no help. Help! why no loro?

"il" is the definite article used before a masculine noun (singular). i.e.: il ragazzo

When the noun starts with a vowel, we use "l' " instead of "il". i.e.: l' uomo

"i" is the definite article used before a masculine noun (plural). i.e.: i ragazzi

And "gli" instead of "i" is used when the noun starts with a vowel. i.e.: gli uomini

Dove si trovano i polli is like saying where would one find the chickens. It's more used for directions from what I was told. However it's wrong since the sentence is asking where are the chickens are kept, not where would you find them.

Be sure to always click on the lightbulb icon every time you start a new skill. It's where the lessons/tips are. Your question is answered at the top of the page for Basics 2:

Use Gli for masculine nouns in the following cases: --before vowels (like for gli uomini) --before words starting with Z --before S+consonants (like in the clothing lesson, when it was gli stivali) --before words starting with GN, PN, PS and other weird words we probably won't have to worry about for a while

Basically, wherever we'd use Lo or L' (lo zucchero, l'animal) in singular, it seems we'll use Gli when it's plural.

Use the i (or capital I) before plural masculine nouns when they don't have the exceptions noted above)

(All the feminine definite articles are apparently "Le" with no special pre-vowel situations.)

I think they are talking about the owners of the chickens. They=chicken owner
