Blue-kote to prevent pecking and cannibalism on injuries
Scoop for the feed
Someway to elevate or hang your feeders and waterers (keep them A LOT cleaner). I use 6 quart horse feeder pans (kinda like giant black rubber pie pans) and invert them and stick feeders and waterers on there.
If you live somewhere cold, get a water heater base or heated waterer for winter ... not too far away
Latest edition of Backyard Poultry or Hobby Farms might be nice too
