we will be hatching about a dozen bantam chicks that include Showgirls, Silkies, Frizzle and regular cochins, and Golden laced polish this summer. we live in San Antonio, Texas where it gets VERY hot in the summer usually 95-100.5 during the day. We will be building a good brooder out of wood and chicken wire. We were wondering can we put the brooder out in the coop with a light turned off unless it gets kind of cold at night and put them out there at a very young age? Would it be best to keep them inside for 1-5 days? Thank you!!!
