My sister was holding one of my 7 day old chicks, (one of the biggest, with the most feathers, and the most protective) and she said "Luna just sneezed again" I didn't hear it, and neither of us know what a chick sneeze sounds like. She says it was a sound, but not a chirp. She's really healthy (as far as we can tell) and we've only lost one chick, 3 days ago, and none since. If she is sneezing, what do we do? I know we should we have a "chicken first aid kit", what should be in it? Thank you much!
