I am very new at this and find myself on an emotional roller coaster.We have 16 chickens 8 sex links (3 wks on 5/29/11) 2 Buff Orpington, 2 Buff Brahma, 4 Silkies (2 wks as of 5/25/11) A couple of days ago I had 4 chicks that seemed to be "sneezing". We changed the bedding from shredded paper to pine. Almost right away the 2 sex links seemed better (I believe the ink from the paper could have caused the problem). The other 2 (BO) got sick 1 day or so later and eventually got better later. Like I said we changed their bedding and now I give them poly vi sol without iron in their water. I also give them a bit of plain yogurt in their food. They seem to be better. Yesterday I didn't notice any of them sick. This morning one of the BO was breathing with her beak open but didn't seem sick. After doing that for a couple of seconds she'd close her beak and breath normally. Is that normal? What are some "normal" noises they might make? I was thinking of adding more chicks but don't want to do that if any of them are sick. None of them seem lethargic or anything. I think I might be a stressed out chicken momma. Does anyone else like to just sit and watch them?
