Hey quick off the topic question. How old do chicks have to be before they can leave the brooder and heat lamp? Mine are about 5 weeks and feathered out (except the heads)
Fully feathered and used to whatever temps they are being put into. If it's warm out and comparable to the temps they were at in the brooder, your good to go. If it's cold out and they've been at 70 degrees then no.
