I have a 4 or 5 day old baby chick who's been acting strange the last couple of days. She started by opening and closing her mouth repeatedly all day yesterday but acting mostly normal otherwise, slightly lethargic. Today she's been chirping nearly nonstop, some of the time with eyes closed. It sounds like a tiny car alarm. Which led me to expect the worst, but I saw her eating and drinking on her own not even 4 hours ago. She's been drinking a probiotic and electrolyte water since Tuesday when I got her and has been on a non-medicated organic feed.
