This a very timely topic for me. My main worry is my pullets (10 weeks) are so used to being let out to free range that they may freak out and start picking on each other when they are penned in the run for a week. In addition, I expect temperatures to be consistently in the 90s and 100s in July so keeping cool water available will be a challenge. I hesitate to ask my neighbor to change a 3 gallon waterer everyday since that defeats the purpose of having a waterer of that size.
