My broilers are two weeks old. I was wondering when it would be okay to put them into my outdoor brooder? It is in the upper 80's - lower 90's here during the day (with the occasional discrepancy) and can get down into the 60's at night. Currently they are in a smaller brooder in my husband's shop, but they are quickly outgrowing it. The outdoor brooder is on our covered porch, so it is protected from rain, so they would never get wet. Thanks!!
