She is about 7 weeks old. We let them out last night for an hour or so and the put them up. It was the second time to do this. This morning I noticed she looked odd, but no strange sounds and she was eating and drinking. My husband and I went to check just now and she looked strange enough for him to worry. She walks and eats and drinks. He poop looks normal. She is making a strange sound. I have never heard her make noises and this one is different from all the rest of the chickens I have. She is sneezing, but not constantly. Just every now and then. He chest sounds razzy. Definitely not right. She looks like she may be molting, but that wouldn't account for the strange chest sounds and the sneezing. Any thoughts?
