Yesterday my week and half old chicks slept most of the day. I was slightly concerned(usually they're really busy), but figured they just needed rest from growing so fast, but last night I went in to find one of my australorps lethargic and week. All the others seemed fine, so I checked her over, but couldn't find anything outwardly wrong, but noticed that when I place her back in the brooder she laid with her wings puffed out. The rest didn't really look hot, but I didn't know what else to do, so I raised the brooder lamp and gave her some sugar water, within a few minutes she was perking up. I waited another hour checked her, she was still punky, so I gave her more sugar water, and let her rest. When I checked on her before bed she was up and eating, and this morning acts just like her old self. I'm assuming she was just too hot, but would love to hear from some you chicken experts out there.
