It is helpful to have them brood out of the house!I do too. Need to rip so OSB board for sides to a utility table to make a brooder at a level we can maintain without bending. Brooders that we've been using have been moved outside and the houses are not ready yet so we are putting one out in a utility room that has its own heating and cooling system making it a separate room from our living quarters. We can brood there until feathered out well enough for our mild winter temps. I've got to make two of them as in a week another brood will be hatching. I'm flunking Chicken Math1002.
I have chicken math under control here but it was very hard to do!
