MKR, My oldest tom is actually prone to colds - has been since he was small. And the other tom is a diabetic so I think the mixture of his lowered immune system and cold weather has caused him to catch it off the older guy. They really loved their chicken the other night(as did the two girls - well, it's only fair!), and are actually eating pretty well so I'm more concerned about them being miserable because they have colds TBH! They are both using their smarts pretty well and sleeping it off in warm places as far as I can tell!
