Hi all as you know we got the two sulcatas a few weeks ago, all is going great, they are active, eating good (both have gained over an ounce since we've had them) but have a question that we've not been able to find any information on: About a week ago, the smaller of the two did this but tonight the larger one did it three times pretty aggressively, let me explain what im talking about, Ive been feeding them bits of their dinner by hand they usually take it an gobble it up, but like I said the one did it last week and tonight the other, instead of taking the food from my hand they quick as lightning suck their head in and lunge/run forward ramming my hand with the front of their shell. The one tonight actually knocked the food out of my hand. Any ideas why they are doing this?
