First off thank you all so much for all of the valuable information. I've learned everything I know about chickens from all of you. I have 3 chickens that are now 4 weeks old. Each day for about 4 hours I've been putting them in the outdoor coop/run to get used to it and get out a little. .. I live in CA and it's warm. I have them in a brooder in my house at night when they aren't outside. I have vertical chicken nipples set up in the run and read on here how to get them to use them. 2 out of 3 of the chickens have figured out how to use the nipples, but the third one has no interest in it at all. I've watched them for many hours and two of them use the nipples and the third one doesn't even seem to notice or care that the other two are getting water. We have tried to tap her beak to the nipples but she doesn't want anything to do with it. When we put her back in the brooder in the evening she drinks from the water dish for a long time cuz she hadn't drank anything for over 5 hours. This has been going on for over a week. I've tapped the nipples when she's nearby, but just runs away from the water. I'm worried about her when she goes into the coop/run permanently in 2 weeks and was wondering what I could do to get her to use it. The other 2 use it regularly, but she's either not around or just walks away when they use the nipples. Everyday for over a week she hasn't used the nipples at all when she's out there for many hours. What do you recommend I do to get her to figure it out? Thoughts, ideas, anything will be helpful.
