Lilly is a 12 week old Blue Cochin ... 2 days ago was running around with her flock mates happy go lucky. Yesterday I came home from work and she was sitting in the corner of the pen by herself. I walked over to her and she let me pick her up (unusual). She looks like she has the "blues" and does want to mingle with the others. I checked her out .. not lice or mites but has a poopy butt .... messy feathers around her vent. Yellowish. Is this a sign of worms? I cleaned the coop and pen and did not see any unusual poops. Is she too young for Wazine? I cannot find any Valbazen in the area so I did order some online today but that won't be in for a week. I'm worried. She is just sitting at the door of the coop by herself. She is not really interested in her food. She did eat some corn muffin.
