I have two 5-gallon buckets, one inside and one outside, each with 3 nipple waterers. I had a 5-gallon galvanized waterer inside the coop, but it was a hassle for me to fill and pack inside, so we replaced it with a 5-gallon bucket with 3 nipple waterers. My egg production has dropped from an average of 15 eggs per day to as low as 3 eggs per day. I know some of the girls are molting, but not THAT many. I put the galvanized waterer back in the coop today and it looked like those poor hens hadn't had a drop to drink in days. They swarmed the waterer. Now, I KNOW that they've been using the nipple waterers both inside and outside. Is it possible that they are simply not getting enough to drink from them? I sure don't want to have to start packing that heavy galvanized waterer again. My back is killing me.
