I had 15 shipped, half were barred Rock. Got them today and one was pretty sick already. She has passed away. Now two more are looking rough. Clicking/grinding sound coming from chick. Appears to gasp for air and throw head a bit. I am terrified and trying to soothe her but nothing is working. I tried some water (with nutradrench and some sugar) with no results. Feeding with a medicine dropper could she has aspitrated ?? The first chick was doing all the same things and I never had a chance to give her the dropper. I've got 5 healthy left and the woman who got the other half says hers are fine. I don't know what to do! Why just the barred rock?
