I have a three week old Brahma and a 1 week old Ameraucana together. They have grown very attached to each other, but the 3 week old keeps stepping on the 1 week old. It's probably fine but I can't stand to see her getting stepped on like that. I have tried separating them but they cry and cry for one another. Another problem I'm having is I was using a heating pad for them when the weather was warm, but it has started getting colder so I set up the heating lamp and now the older one doesn't want to sleep which keeps the baby up. Is there anything I can do about either of these things? I know having chicks of different ages isn't preferable, and I've never done it before. Perhaps I am being too protective and all I can do is just leave them alone and let them grow, but I just want them to be happy. I would just like to hear other people's thoughts.
