It has been a tough year in the poultry business, with supply outpacing demand and feed-grain prices rising substantially. But producers are hoping all that                changes when the summer cook-out season starts.
 The seasonal upswing in chicken consumption, along with the anticipated jump in spot-market poultry prices, could bring some relief to producers whose profit                margins have been slashed by surging corn and soybean-meal costs.
 Rising feed-grain prices, accelerated by the diversion of corn to make ethanol, have pushed up the cost of producing a live chicken by as much as 65% over the past                two years.
 Three factors make analysts more optimistic:
 Companies are cutting production, weekly egg-set numbers are declining (egg sets are fertile eggs placed in incubators), and prices are responding positively to                the decreasing supply.
 The production slowdown is a response to the surge in feed-grain prices last fall.
 Profit margins at producers will not improve unless spot-market prices for chicken move up fast enough to cover costs paid for corn and soybean meal to feed                chicken flocks.
 Production cutbacks and seasonal demand have helped fuel a 20-cent increase in boneless, skinless breast-meat prices to $1.46 a pound. Prices are expected to reach                at least $1.80 by summer 2008.
