I got a brand new Bearded Dragon about a week ago. For the first couple of days, he was absolutely great. He ate well, including eating his veggies, hit temps were great, and he was generally really docile. He has Shed about twice now and I gave him a couple of baths to help the shed go better, which they did help with. However, he has started acting really strange lately. He will do this thing where he follows my hand with an open mouth and puffing out his neck (though the neck part does not turn black to indicate bearding). Sometimes he's completely fine and doesn't react whatsoever to my hand, but other times he is very upset with it. Is this his personality? Should I take him back to the store and get a new one, or is it something that I can easily fix? I just want my beardie to like me, and this behavior does not seem in line with everything i've heard about their personalties. Any advice, tips, or answers are GREATLY appreciated. Thank you!
