I quit lurking.... brooder is setup and ready to add chicks. 4' x 4' 2' hi had lots of old wood to piece it together. used hardware cloth but for a few inches used the stuff we use for stucco. had a few windows with piano hinges so I put that on two facing sides. might have to play with the heat lamp to get temp to 90 at night. it is already 90 during the day.
