My chicks are approximately 3 weeks old and have most of their feathers. I have had them in my house since we got them in a sealed off room. In the last few days the smell and the dust has gotten unbearable! I want to move them into the barn so badly today, but it is just below freezing outside. I have 2 brooder lights. Will they be okay if I move them out? The temperature is supposed to finally warm up tomorrow, but I don't want to wait. Of course, I will if I absolutely have to...
