My 8 week old and 6 week old chicks are sneezing. Not all the time but every so often. they are both active bright eyed and no mucus is present. I haven't heard any wheezing or anything like that. They are inside right now in their own room in a HUGE watermelon box. Their box is clean their food and water are kept up off the shavings and water is changed twice a day. They are acting normal and active. Should I be concerned? Thanks for your help. They are shedding their baby feathers right now and I'm wondering if that might have something to do with it. I try to pick up all the feathers they shed but I know their is dust I can't see that goes along with that. Do you think that's the issue or do you think I've got a bigger problem? I have some tylamox powder (mix of tylan and amoxicillian) but I'm hesitant to use it if its not necessary. Like I said they are active and seem well except for occasional sneezing by both of them. Any advice is apperceiated. Thanks.
