We got 6 babies the day after Easter. Not sure how old they are, but they all have little wings now. Well, all except one bard rock. (We got 3 RRR and 3 bard rocks). She looks puffy and fuzzy. I let them out of the box to run and spread their wings. One BR just stood there. I got a closer look and this looks like the littlest one and still just a fuzz ball. She stood still with her eyes closed. I put her in a different box, fed her some sugar water, and some yogurt, but she is still just sitting there. I just held her and she is breathing heavy and loud. Do I keep her separate by herself? Can one stay alone? We lost a grown RRR (1 of 2) on Easter Sunday and my 7yr old son got very depressed, hence the 6 new babies the next day. This lethargic one is his, of course. Now he is so bummed and down. He keeps saying his chick is going to DIE. PLEASE HELP!! This little one cannot die!! edited to add: The chick has loose, stringy, white diarrhea.
