In English, we would more likely say "fried chicken," thinking of it as an uncountable, like pork or beef.
"Ibu memasakkan kami ayam goreng."
Translation:Mother cooks us fried chickens.
Yes, I agree.
It doesn't have to be more than one chicken.
One is more than enough for me :-)
Mother cooks us fried chicken. = not accepted, reported
Fun titbit: In Indonesia 'ayam goreng' is non-battered or breaded chicken usually marinated in tumeric or sweet soy sauce. If it's 'fried chicken' then it's KFC style battered chicken.
