Friends, We have now done something we worried over doing but had no choice. Our girls are terrible feather pickers and feather eaters. All ten of our girls now have peepers on them. They adapted immediately to eating and drinking and jumping around on their roosts. I would recommend if you have to do this, do it to all your chickens at the same time, not just one or two. In our case it was imperative and now, I am truly glad we did it because they did not get hurt or traumatized. I do not know yet if they will learn how to drink from nipple waterers but will post back again in the future, if so. Currently they have water bowls and food bowls. Just thought I'd let you all know of our success.
