I have a hatching of 6 chicks that are 3 days old. One of my chicks I noticed on day 2 had 1 closed eye. By nighttime, both eyes were closed and stayed closed for the rest of the day. With both eyes closed, she obviously had trouble getting around to find food and water. The next day, I went outside to take a picture to put on BYC and both eyes were open! Case solved I though! Then today, both eyes are again closed. ANY GUESSES ANYONE?
