This is from a 4 week old Buff Orpington chick. I'm raising 4 in my garage in a dog crate. They were all on medicated feed for the first three weeks of their life. Once they finished, I mixed the remaining bit with regular chick starter and that is what they are on today.
All are acting fine, eating, drinking, chasing each other around. I have noticed a bit of light sneezing but I also just gave them a big bowl of fine dirt to dust bath in and it's their favorite thing. They are in there all day long so I'm pretty sure the sneezing is just from dust.
If this doesn't look right or looks like Cocci, what do I do to treat?
