I need a little help. I went to the coop this morning and found two of my 4 month old SLW being roosted on by the other chickens! One hopped up and ran off after a few seconds but the other could really get out of his spot on the corner. He was droopy, and only took one sip of the water I offered. I set him down to see what he would do and he sat, couldn't really pick up his wings and when he tried to walk he went zig-zag (like he was drunk). I noticed some poo on his feathers around his butt and black speckles on his comb. I did not get a good look at them, so it may have just been dirt and poop from being sat on all night. I leave town tomorrow morning for a month and don't know what to do. Any advice is greatly appreciated.
