Depends on how the food and the service is. If it's awesome, I think a hundred or two is fine. If it sucks, nothing is fine.
We hunted Mexico last January and hired a little old lady to cook for us for the week. We loved the food, and she really tried hard to make stuff we liked to eat. We pooled our money and tipped her $600, over her wages of $25 per day.
Went to a camp in Colorado 5 years ago and hunted deer with an outfitter. My wife had the tag, and the food was so terrible, and the shack we stayed in was so bad, we got a motel and ate out the rest of the hunt. Needless to say the cook did not get a tip.
I run a camp myself, and it's interesting how much people tip.
Most guys tip the guide $200-$500 and the cook gets anywhere from nothing, to $200 with $50-$100 being the most common number.
