I talked to the person I got the four chicks from and she said her chickens has the sniffles too and she got cold medicine for them. She said it was chicken cold medicine she got from a chicken website and that she out it under their wings so they would inhale it? I couldn't keep talking to her as we were interrupted but WHAT?? What kind of cold medicine could this be?? If she believes her chickens have a "cold" then mine most likely do too!
