First timer here . I have had a bad run with temperatures and the brooder. When leaving the house yesterday we lost two chicks ( both day old seemed to have mobility issues .) When the sun hit the side of the brooder i think it got too hot . We're making due with a large, dark purple plastic tub until we can figure out something better. The heat lamp was originally at 18 inches but I think that was causing really high temps . Now they have been moved out of direct sun , the lamp raised and shifted to one side creating a bright and shaded name. All morning they've been all around, eating drinking etc . Now they are almost all on the dark side cuddled up sleeping. Should I worry that it's too hot again or are they just doing what they need to do , avoiding the direct heat for the time being ? The lamp is set pretty high now so I don't think it's blistering . I guess I a worried to leave . Any input ?
