The youngest chick is 1 week old today. Golden Penciled Hamburg. She is the tamest and has always just fallen asleep when I hold her. Just now she was 'sneezing' with a slight slidways head shake like you or I might do when we sneeze. She looks to be breathing heavier than the others. Still pretty slight, but if you watch her you see it. I thought maybe she was just nervous but as she fell asleep in my hands her whole body was 'breathing' which makes it more noticable. Next smallest chick doesn't seem to have the 'whole body moving' to breath. They are on the medicated starter food. Have wood pellet bedding, no dusty shavings. Is there anything to do for her? Does she have a cold? Is she getting something? Does she need to be isolated from the rest of the chicks? any help appreciated. I'd hate to lose her.
