Something is wrong with my 5 week old silkie and I can't figure it out. Over the weekend we took the 5 week old chicks outside for the first time (3 days in a row) to adventure and meet/mingle with the older bantams that they'll eventually be moving in with. All of a sudden yesterday morning, I noticed my little silkie not quite acting like herself. She's been standing around with her head tucked close to her body and making that cricket/chirping sound constantly... like she's crying? She walks around, eats and drinks. But mostly just stands out of the way of the others or cuddled with them and chirps. She's also sleeping more than usual with her head tucked backward into her back (I know that's normal but shes ONLY sleeping that way.) I also noticed the 2 little roos of the group have been kind of "guarding" her. I know this might sound tough to diagnose. I've watched her and examined her now for 2 days and I cannot see any other behaviors/symptoms to share. I just know that she isn't acting 100% normal and healthy. Does this behavior sound familiar to anyone? Is there anything I can do to make her feel better?
I have a probiotic chick boost in their water already and I've tried an Apple Cider Vinegar/water mixture. She doesn't have pasty butt. No injurys from what I can tell. I don't know what else to do, specially since I really can't pin point what the issue might be.
