I am getting ready for 15 chicks and 5 guineas. I have a garden tub that we don't use. I was thinking of lining it with something (?) and raising them in it. That way they will be safe and with me in the house. My husband will rig a heat lamp over the tub. When they start to get too big for the tub I will keep them in the coop. Does this sound O.K. or am I crazy???
