Hi all, long time no question. This morning, I go out to check on my flock to find my Polish pullet, Dizzy, acting very lethargic. I've immediately isolated her inside, in a cage with 20% chick starter, and water with some ACV in it. So far, she's shown no other symptoms at all, and she hasn't excreted yet for me to check for blood (cocci) or yellow-ness (worms). She was acting %100 right as rain yesterday, and none of my other birds (one 10 week old Polish cock, and about 15 various breeds of 5-week olds) are showing any symptoms of illness. Generally, just holding her head in (*sigh* yeah. Kinda vulture-ish), drooping her tail and wings, and acting disinterested. No crying, not acting in pain at all, and still drinking, though she didn't seem remarkably interested in her food. She'd peck at it but not a lot. Possible things of note; It was just two days ago that I integrated the younger chicks into the two Polish's pen. No babies were acting sick at all. No stress or fighting resulted from the integration, aside from very minor and expected pecking and such. When I first noticed Dizzy was acting all droopy, I immediately picked her up and checked her vent. Normal, no discharge or crawly things, and not to be graphic (well, we're all chicken owners here), but it seemed as though she'd gone and the stool'd gotten caught in the fluff right around her vent. Completely normal stool, brown, solid, white urate, no blood. Was raised on nonmedicated feed. Go me -_-. Crop is normal. Comb and wattles seem normal, eyes clear. Any ideas of my course of action? Seems like time is of the essence here. Would treatment for worms or cocci stress her out or harm her if she doesn't have these ailments? Thanks!
