About two pounds of chicken (1.9839375).
There are 21.43 stone in 300 pounds.
Are there side dishes? If all you are eating is chicken, each person may want three pieces, so you will need 90 pieces. But if there are side dishes then one piece per person should suffice. A chicken has a back, two legs, two wings, two breasts, and sometimes the wishbone is cut out separate from the breast, making about seven pieces per bird. Five chickens gives you 35 pieces, so you might have some leftovers. If chicken is all that is on the menu, you might want to butcher about ten birds.
