My brother and I are new to raising chickens. Almost two weeks ago, we purchased 21 chicks. Tonight, while letting them run around, we noticed about half are sneezing. We were going to go to Tractor Supply tomorrow and get probiotics to put in their water, but we're wondering if there's anything else we should do? Also, one of the larger ones (we think he's a roo) has been pecked at a bit between where his neck and wing meets. No blood, but definitely weeping. We've been doing hours upon hours of research about them for a while. Just wanting to make sure that a simple saline solution and antibiotic ointment is best for him. We've already separated him from the flock.
