My flock has been decimated a lot over the last week or so, I've lost 2 broodies that were with chicks and another hen to a weird disease (necropsy is under way). A very determined stray cat has made an all-you-can-eat buffet of the baby chicks of both groups when their moms died (my fault, didn't secure them enough). Now I've got 3 chicks that are 6 weeks old from one hen and only 1 chick, 3 weeks old from the other hen left. The 3 "big" ones are together in a cage since yesterday and the one small one is in a cage of its own since today. Should I put it in with the others? They are much bigger. And there is still the question if either one caught their moms' diseases. On the other hand, the little one is lonely and chirping. Can one raise a chick alone? What should I do?
