Crawfish boil quantity question please

120 lbs, with sides.
All from La., increase to 150 lbs..

Might have enough leftovers for a couple crawfish omelets at breakfast and a small dish of crawfish hash browns for supper,, might?

If you average 5 pounds for each male and 2.5 pounds for each female, that's 72.5 pounds.

Depending on sides and how much they eat, you can get away with 2 sacks. If they can put "em down, get 3. That'll be more than enough and leave you decent leftovers.

I use the following as a guide -

5 lbs for adult and teenage male
3 lbs for adult female
2 lbs for teenage female

Then add 5 lbs for every 10 people.

In your case that is 83 lbs. I'd probably just get 3 30 lb sacks. But I like having a bit leftover.

This is assuming plenty of stuff to go with the crawfish.
