It's not Spanish (or, if it is, I've forgotten even more of the language since I left school than I thought I had!)
It appears to be a colloquial form of Portuguese (possibly Brazilian?) which, unlike the other languages derived from Latin, uses 'no' to mean 'on' or 'in'. So you appear to be asked to do something with a henhouse or chicken coop (because that's what 'galinheiro' translates as!).
It's probably spam. Ignore it. If the sender really wants to be your friend, she'll write in English (even if it's only of the sort that online translation sites can provide).
