I would like to change our watering system to the nipples. Our chicks are almost 4 weeks old. I assume it would be easier for them to get used to it the younger they are? My plan is to have the nipple waterer inside the coop, and a regular waterer outside (in case the pulley door closes to go inside). I have read this will cause issues for them not use the nipples...but if I install the outdoor one once they get used to the nipple, will it still cause confusion? (Am I making sense?) We have 9 chicks, how many nipples would be best? We were thinking 3 or 4. Also I have been letting them have some bits of romaine every other day. I tear it up nice and small for them. Is there any reason they couldn't have this every day? This morning they almost swarmed me as I was putting the plate down. They are loooooving it. Is it too early to throw in a small handful of dried mealworms so they can find them throughout the day? I've read this encourages foraging...which makes total sense. Thanks!
