Hi all, I'm fairly new to the chicken community....I have 3, 5 week old chicks. I'm looking to get a hanging watering system for them, since they scratch to much bedding into their little chick waterer. I live in the Pacific Northwest and winters can get cold sometimes....my question is, should I invest in a nipple watering system and just hope the water doesn't freeze in the nipple during the winter.....or should I get a traditional hanging waterer?
