Sulcattas stay out year round... they all have there own burrows (I should take a pic inside one, just to show you how huge and deep they are), the redfoots come in if it gets below 65F. Our winters are not that long, probably average of 1 month 55-60F weather. The birds are there, but we dont try to breed them, actually we're trying to sell them. Other than that... we really want to focus on turtles and tortoises)
