Yes, and they're more likely to be killed by the anemia so youll want to get on this quick to avoid that.
Treat them all with sevin dust or (better yet) poultry dust, including the bedding. Shake it into the bedding good so that the area isn't dusty. Remove the babies and other birds while you're doing this, wear a dust mask.
You can use adams flea spray or dip on adults but I wouldn't on the chicks. I think the sevin would work.
