I got eight mixed breed chicks Saturday (they are about one and two weeks old) and they have all been doing good, until today. This morning one (it is one of the older) was a little sluggish, but was moving around and I did see it drinking. It has gone downhill all day. I've tried to get it to eat with no luck. I have been able to get it to drink (water and a little sugar water) up until around early evening. I'm worried about the others now. I've been watching them and they are eating and drinking, and scratching around. They are outside in a secure warm coop. Around 95 degrees in the warmest spots and around 80 degrees in the coolest areas. They have been sleeping well away from the light today, with exception of the sick one. They are eating Dumor Starter/Grower Chick feed and they are catching bugs that get inside. I have been providing grit in a separate bowl and some on the board the feeder is sitting on. The bedding is hay and pine shavings. I moved the sick one inside under a lamp, but it continues to go downhill. Anything I should do with the others or something I should watch for? Thank you.
