I dip my cresties noses in the cgd once for the babies and three of four times for the older one.. im sure they could eat on their own but it makes me feel better knowing they are getting something.
We keep ours at room temperature (approx 70-72 depending on time of day) no extra lighting or heat source. We also do not feed any crickets at this point, our cresties are one month and approx four mos.
