I have a flock of 1 1/2 week old chicks. One of them started sneezing a few days ago. It seems to have spread a bit, but not much. She's still eating and drinking and peeping and running and stuff, but sneezing. And, today, when I was holding her, she sneezed and a bit of mucus came out her nostril. I've been keeping them on chopped straw. I thought it might've been the straw, so I changed it this afternoon. To soon to see a change. Help! These chicks are my world; I love them!!!
