Hey Sydney , have you considered using sand as a litter ? I put mine out on the grass , supervised from about 10 days. In this weather I would be giving them a little more time each day away from the lamp. How old are they now ? They should be ready to go out at around 6 weeks, for good. So long as they are feathered in. The lamp should be getting raised a little each week . You would be suprised how early they learn to dirt bath when they are with momma. Nice to have you back.
