So all of these threads recently about chicks going from the brooder to the coop reminded me of a question I'd had... So we're going to finish building our coop this weekend, and finishing securing the run. After some reading, I think I've decided to get a bucket/chicken nipple watering system, but currently my birds are not using the nipple system. Is it difficult to change that up on them? to go from a regular water system to the nipple system? and how did you teach your birds how to use the nipple system? Thanks in advance!!!
