We have a Dominique chick that is 2 weeks old. I had everyone in pine shavings and think the dust got stirred up with everyone kicking because we changed the bedding. It was the bottom of the bag and everyone was going to town. 2 hours later went back and this little one was sneezing. Took them out of the shavings and 3 days later he is still sneezing and his breathing is shallow and rapid and a slight clicking when I listen. I'm now worried it might be an infection setting in. I have ACV 1/4 teaspoon in the quart of water along with vitamin/electrolyte/probiotic mix (rooster booster) and 3 drops of VetRx so each drink gets some on the beak. I have Tylan 50, but can I add it to a little bit of food or does it need to be injected? Worried about muscle damage in this little one. Is it once a day or twice a day? I'm pretty sure he needs .125cc's due to being a little thing. Anyone have any advice or know?
