Our chicks arrived today (3 BR, 3 RIR). Our supplier suggested putting a 1/2" dowel in their brooder so they can roost. I am just not sure how high to put it ar when I should expect them to use it. I placed it about 4" off the brooder floor. I don't know if this is too high. I did try placing a couple chicks on the dowel so they might get the idea but they did not like that.
