Clean beneath the cages.
Again, this is usually automated with machines and conveyor belts.

Options are: --If you can find blowers at department stores, use them. Clean beneath the grates and be careful not to touch any of the milder steamed items, as some of the raw skin will be sprayed in the steam.; --Provide 1/2 a bucket of milk for feeding. You can buy milk at any pet store or have one in a supply room.; --Ensure all feeds are cleaned and the cage is clean. Farm companies use blowers to perform additional maintenance checks.; --Inspect the flock daily and contact a veterinarian at any sign of illness. Since the poultry houses are crowded, disease can spread quickly.;
