how old do my chicks have to be before i can bring them outside during the day for a little bit? and im talking like an hour or so? also.. i live in new england and so its actually been pretty chilly. how long can they be out of the heat lamp so i can bring them outside for a bit? sorry.. haha but one more question: this might sound silly but ive been afraid of them running away because i just hatched like 15 baby chicks.. if i bring them outside for the first time, should i make sure its an enclosed area? will they scatter? stick together? follow me? thankyou!
