Give him 5 of the items he's, ( I presume ) asking for and he'll give you a chick. Chicks will then give you eggs and chicken meat everyday. I was able to have several chickens running around the farm.

Yeah I think I saw he was asking for beef...was one of the few English words in the dialogue.

“A maximum of 7 chicks can be exchanged. The required items are:
① 10 pieces of beef
② 10 bottles of milk
③ 10 cans of honey
④ 10 pieces of pork
⑤ 10 pieces of lamb
⑥ 10 grass
⑦ 10 portions of soil”
