Our chicks are 2 1/2 weeks old. They all arrived two weeks ago in perfect condition... We are so in love with them!! What did we ever do before??? They have been been inside the house in a brooder box for the past two weeks although we do let them go outside in a pen for a few hours each day in morning and night when it's not too hot. We have let them out during the day and they seem to be way too hot even in the shade with a breeze... I let them sleep outside for the first time night before last. The brooder box had a lid and a light for heat. They were fine so I let then sleep outside again last night. I lost one of the babies last night and I feel so bad! We have been taking such careful care of the babies. Here it's too hot during the day and although it was about 80 at night that is the only think I can think that happened. I couldn't bring myself to tell my 11 year old daughter that we lost one of them.. and I am hoping she won't notice... They will be sleepin' inside for another week or so... Any advise on raising chicks in the Arizona heat??
