Hi all, I'm super new to this chicken thing so I'm asking for some expert advice. I had 6 Red stars that are 14 weeks old (I bought them started) and 2 4 week old Black Australourps (bought from my feed store). We are in the process of building their coop (almost done) and so they have been housed in the garage for the time being in an area with newspaper and large pine shavings. One of my Red Stars died last night. I had noticed that she was getting less interested in food the last couple days. She was also sneezing with a little mucus coming out her nose (I noticed this esp when I went to dispose of her). Anyway, like I said, she died last night and I noticed today that a bunch of my other hens are sneezing as well (I haven't noticed the australourps doing so yet). They have not had any signs of eye congestion or anything as of yet (including the one that died). I've tried to do some research to understand how to combat this illness, but all I can figure is that it's a respiratory illness of some sort (I don't know which one). I would really hope not to have to cull them all before I even get started with a backyard chicken hobby. :-( I've noticed a little loose droppings now and then. I'm so new to this chicken thing, I don't know what's normal. I clean out their area every other day to try to keep everything clean to lessen the chance for disease until they can get into their new coop, yet here I am. This morning after cleaning out their area again thoroughly, I added ACV to their water and gave them a hot mash with oatmeal, probiotics, honey, egg and a sprinkle of garlic. Please help!
