Good Morning, I have 21 chicks that will be 3 weeks old tomorrow, they have grown out of every inside container from a tote to a kids swimming pool. I have a nice brooder set up in the coop. The weather here is crazy, one day 65, next day 32 with snow. It is to be in the 40's to low 30's the next few days. I have a few heat lamps, what do you think that their chances will be in the coop with heat lamps and a barrier. I can but blankets over the hardware cloth if I can't get the temperature regulated. What is the lowest temp that they can have? I need to move them, my basement smells bad, I change the litter regularly, but they are growing and the heat lamp heats the poop and makes it stink!!!!
