What you will need
Since chickens don't drink at the same time the most you will need for a very large flock is 8 to 10 nipples. They run about 2.00 to 2.50 a piece.
A 5 gallon bucket with lid
joiner to attach tubing to bucket and pbc pipe.
That's it. It's that easy . I love it . .. About once a month I do clean the bucket since we have very hard water. Once a month is so much better then one to two times a day.
Here are some pictures to help you if your intersected in making one
Hope the pictures help. This is my husband field of talent, not mine.
