I've got a 6 or 7 day old chick that just is not doing well. I got her at a flock swap and she seemed fine the first two days, but I noticed she wasn't eating and I've been trying to encourage her by giving her mash of water and chick starter. 3 days ago I noticed she had a wonky eye which looked like someone had pecked her. It didn't look infected or watery but it was closed more than the other eye. I wiped it gently and I've been keeping an eye on it and today she doesn't open it at all...it actually looks like her eyelid has sealed shut - though it's not swollen or irritated looking at all. She flaps and peeps when picked up and will drink if I encourage her to (her water has save-a-chick in it). She will also eat if I dip her beak in the mash but she'll only take a bite or two then turn away from the food. She is in a brooder with many other chicks, all who are doing fine except her, and she is the smallest although there are 2 others the same age as her and 1 who is perhaps a day younger. She has the option to eat and drink in the brooder but I've been pulling her out to encourage her to eat and drink separately several times a day. Any suggestions would be welcome.
