i picked up 25 white leghorn chicks a couple of hours ago from the post office. temp here is 50s outside. chicks were shipped from Iowa last monday. while most chicks were up and about running, drinking and feeding, four were lethargic. one is already on its side (separated and given a few drops of sugared water by medicine dropper). the 3 others were mostly still with eyes closed. one was like gasping - opening its beak, straining its neck. what can i do? give drops of water? isolate? (i have an outdoor 5'X5' brooder, with a 3'X3' hover, fitted with 100W and 60W lamps, which i had running since last night). will the lethargic chicks better off isolated in a warmer place inside the house or joined with the rest of the flock, with usual access to food and water? thanks!
