Hi. The internet is great but sometimes there is too much info. This is my first time with baby chicks. So far so good. I have had them 2 weeks. I'm guessing they were about 3 days old when I got them. It has been really hot here in the 90's so I have let them out into the coop during the day. Is this bad?? They came in at night by themselves. At 3 weeks can I start letting them go outside by themselves while I go to work or should I keep them inside in the coop? I feel the outside run is really safe with welded wire. A door that locks , partial roof rocks around the bottom and wire in the ground a foot out.Thanks for any input.
