I have four 1 week-old chicks and I've noticed two of them sneeze occasionally. I've been taking them out of the brooder for the past few days days, once a day, while I replace the paper towel in the brooder. They seem to love the running around and pecking/scratching at the carpet (they're in the study). I have to go on poo patrol afterwards, but they seem to really enjoy being able to stretch their little legs. Today, I sat on the floor with them for a bit. A couple of them sneezed, I thought it was just because they were eating fluff and not enjoying it, but then a drop of clear liquid landed on my hand after a sneeze. Do you think they have a cold? They haven't been shivering or noisey about their brooder conditions. They eat well and drink well (medicated food and plain water). Other than what they may find in the carpet, they don't get fed anything extra. Has anyone had this before? Am I heading for a major illness? Edit: thought I'd better mention that they're not bedding on shavings or anything, just paper towels.
