Our chicks are between 1-2 weeks old. I took them outside yesterday for about 10 minutes and they loved t! So today I took them outside while cleaned out the brooder so they were out there for about 30 minutes. Well when I brought them back in they were all lethargic. The barely moved when put them in the brooder they were breathing heavily and a couple were laying on their sides. I FREAKED out but remembered some people talking about dunkng ther beaks in water so I dd that and it seemed to do the trick. Can the chicks overheat?
