Bifen IT would be a good choice for grasshopper control. You should start applications before the grasshoppers have a chance to hatch for best control. If you already have grasshoppers you can use Bifen at the highest usage rate of 1 oz of product per 1 gallon of water for the quickest knockdown.

Bifen I/T is used in poultry housing and facilities as long as the chickens are removed from the area while you treat them. You should still be able to use it in their grazing areas with no issue since they are not actually feeding on the grass/potential seeds placed out but on the insects in that area after everything has dried. If you have any concerns with the Bifen I/T usage, another option that is safe to use in grazing areas is Essentria All Purpose. You still have to remove the chickens during the application but once dry is safe to return just like the Bifen IT. Neither product should have any effect on their eggs at all as long as you are following usage instructions. 

Bifen IT is safe for use around pets when used according to the label. You should always keep children and pets away from the away while you are treating, and then once the treatment is dry it is perfectly safe to allow pets to re-enter the area.
