i have a four-five week old RIR from TSC and she just started sneezing... i didn't notice it until today... it's been very warm here, so we moved the chicks outside into a coop about a week ago, and they're all pretty much fully feathered. she has no other symptoms and none of the other chicks are sneezing. it doesn't sound dreadful (it's just some light sneezing), but i'm still concerned it could get worse. she is eating and drinking normally, no noticeable bloody poop or anything... their chick crumbles are toward the bottom of the bag and are fairly dusty... could it just be that she's sneezing because of the dusty food? help!
