Don’t put them in the coop until they have those weird shoulder pad things on their wings. When you are moving chicks you should take one at a time and put them in where you want them to sleep and don’t let them out into the run for 1 week. Put some stuff that they have seen before in with them so they feel comfortable, like their food container and their water container. Stuff like that. And there you go! That is how and when to move them!
