I noticed a couple of days ago that one of my ladies was hissing and sounded like an old man trying to catch his breath (we just moved and with 4 kids 6 and under I could not get out there any earlieR- now I feel terrible!!). Today another is sick and they are both sitting on the ground with their eyes closed and their combs are purple!! HELP!! What is it??? What can I do? We only have four ladies and I would hate to lose 2!
