My chicks are a little over 2 weeks old. It is going to be 93 degrees outside on Sunday. It's 90 degrees in there brooder right now. Could I let them out into a fenced in area for a little bit just to play? It would be a good poultry fenced in area and there are no big chickens around and we would supervise them the whole time. What time did you start letting your chicks out to play?
