Sugar water is fine for a quick fix until you can get something else, but all it is is carbs, no other nutritional value at all. Sav-a-Chick is a better alternative as it has everything they need. She may have been hurt. Did you check her legs? Try to move first one, gently and then the other. Any reaction? If she isn't up and moving today, you may have to separate her from the rest so she can heal. Again, I use the clear totes and this is the reason I do. If one has to be separated from the others, it's very easy to place the containers close to each other so they can still see each other. This helps with adding the chick back into the flock, later after she heals up.Just reading your post....and looking for an answer for my week old with the same symptoms. Mine is just laying there....with eyes shut. She does perk up when I pick her up..and peeps a bit...but not much. I tried to (and she wanted to..)sit up...but then she fell over a few seconds later.(I did catch her.....She also took a little water from a syringe. I am thinking of adding some sugar, too. Although I am thinking mine is injured somehow. We changed/cleaned out the pen today...and gave them some grass time (in a 4X4 area)..and I am thinking she might have been trampled on. She is a little smaller than the others....but there are 21 of them...and they were SO excited with the grass. This bird was one of my more active and busy birds....and this came on while they were all outside. Not sure what to do either...I am new to this game as well....and I see there are SO many things that could go wrong!
Good luck with yours...guess we will both be quickly gaining some knowledge!
One question...do you have your chicks on medicated feed?
