One of the 4 chicks we got yesterday seems unwell. We noticed on the drive home last nite one had a very light sounding chirp all the others were very loud. This chick is approx. 10 weeks old and a Silkie, last nite it was friendly and active just like the others and we watched them all drink and eat before tucking them in for the nite. Today it's still up and moving around I watched it drink twice and appeared to peck at the food not sure how much it ate, but it will sit still bob it's head up and down while opening it's mouth. It appears something is wrong with it. Both eyes are open when it's moving about but when it sits still and does the head bob it will close it's eyes. I'll try to get some video of it and post maybe I'm not describing well at all. We got all four from the same breeder they had nice clean areas and no chicks/chickens appeared to be sick while we were there. Here at home they are in a 15sf brooder that is 85 degree's might get up closer to 90 as the day heats up though on playsand with chickstarter in the feeder and a waterer in with them as well (of course). Any suggestions for what might be happening.. I have contacted the breeder as well just waiting for an reply.
