Update: The kittens are now around 4 weeks old and are exploring everything in their environment. They've learned that I bring food twice a day and will come my way when they see me, along with all my chickens. My husband calls all of them "The Welfare Brigade". While they were still small, the broody was interfering with the mother cat, so she moved them. The broody did break, by the way. When we got a rainy spell, she moved them back, but into the other coop and there were only three of them, so one did not make it somehow. She moved them back out when the rain dried up, but then back again about a week ago and they've stayed with the chickens since then. They all mingle together and seem to get along just fine. In fact, when I feed the cats, I lock them in the small coop so the chickens don't chase them out of their food! I will try to get some recent photos this weekend and post them on the site.
