After my wife and I get moved to the homestead, we are looking at increasing our chicken flock from 13 hens, to somewhere around 25 hens, and then 30 hens the following year.
One of the issues I will need to deal with is how to make sure all of the chickens have access to fresh water in these Texas summers. During July and August daytime temps can reach the upper 90s and low 100s, with night lows staying above 90 degrees.
This video shows how to make a chicken waterer out of a 5 gallon bucket, and some nipples.
I could hang a couple of 5 gallon buckets in the coop, with 2 or 3 nipples on the bottom of each bucket.
