I have 15 6 week old chicks. They came from McMurray and only one died at 3 days old. The others are growing and doing great....until tonight. I noticed a silver Wyandotte laying in the Dust bath pan. I gave them their daily boiled egg and she didn't get up to eat. I got her out of the brooder and tried to stand her up but she can't stand. They were all vaccinated before I got them. I have them in the garage and it is rather warm during the day. I offered this chick some water with electrolytes and sugar but she isn't interested. I have her inside in a dog crate. I'm waiting on my Amish coop to be delivered so they can go outside because I don't want them to get too hot inside. I rubbed some VetRx under her wings. What is wrong and what can I do? I thought they had gotten old enough to not get sick and die. Any help you can share??
