Sorry but was int he beardie ER and my beardo has been ill but now seems better. Anyways saw someone post that they do this once a year and lasts 3 weeks - 3 months. I have had mine almost 2 years and I don't think he has ever done it or nothing has changed. The most that has changed was his breathing and eating when I came home but he went to the vet got on antibiotics and he ate 6 mealworms tonight as he wasn't quite strong enough to catch the crickets oh and green leaf lettuce he has been eating along with the calcium substrate the vet gave him however I disagree that he is calcium defficiant since he did fall and it was only one leg that was a little inflamed and the reason why his color was so bad at the vet was because they told me they would put him in a tank and left him in the box I took him in with only a heating pad and no lights. If I was a beardie my color would of gone bad too. His color his fine now and and changed when he got back into his tank. Anyways I wonder if the brumation thing could have anything to do with how he was when I got back from vacation. here our tems go from -15 to +60 in a matter of days so we get really cold winter days and really warm winter days and while I was gone it got really cold reason for the respiratory infection because the people watching our home turned the heat way down and he got too cold at night. Anyways any info would be helpfull. Thanks!
