Many of us use the Mason Jars screwed onto a base for Watering or Feeding chicks. These are great as the nutrients flow slowly down and last for a few days at a time. The problem most folks have is they sit on the brooder box (or any container) floor and get messy. It only takes a few hours after filling the containers up and placing them on the floor; when they get floor material, poop, etc. on the openings or tray. Let that happen for the first week, only to get the chicks use to eating or drinking from the containers. After a week the chicks are strong enough to stand tall (even stand on one another) and reach up 2 to 3 inches above the ground floor to their nutritional sources. Putting the units up 2 or 3 inches above the floor keeps them relativity clean. This helps prevent contamination from poop, floor material flying into the open sources, and chicks sitting on the container. How Too? Use square (small squares) chicken fencing available from the co-op or feed store. Cut with wire cutters a strip about 8 to 12" inches long and 2" to 3" from top to bottom (the height). I suggest the small square fencing for its strength when all is done. Circle the wire and affix one end to the other end making a ring of wire. That's it. Simple. Place the ring on the brooder floor and on top place the feeder/watering containers. The chicks will find their way and reach nicely into the food base and water tray. Now they will not sit on them, scratch floor material into the tray or food holes, and they last longer in-between fillings.
