Please don't take this as an attack.
Webster's defines "free will" in one word "voluntary". Not having free will would be involuntary like paople breathing or their hearts beating. No free will would make them like plants or an end table.
It doesn't take much to be a breeder of bearded dragons. School kids do it. I have breeder friends that I respect but the vast majority treat animals as a commodity. These types of breeder never take the time to really understand and enjoy the animals they are working with. That is why I have never and never will take even one dollar for any dragon. Those breeders prescibe to your idea that they have no free will and therefore their lives and comfort are unimportant.
Today there are 17 dragons here. They are all my pets. I spend every waking hour that I am not working observing, interacting and caring for them. My boss at work calls it my passion and he is right. They have free will, they have personalities, and they have friends and relationships. Contrary to popular belief, males can get along with other males. But not all dragons get along with each other regardless of sex. Hmmm. Kinda sounds like people. lol.
Anyway, as I stated I have 8 babies hatched between 8/5/07 and 8/8/07. 4 are currently brumating. The smallest weighed 176 when his brumation started. He is the lightest dragon I have ever had brumate. 3 are housed in enclosures with another dragon of the same age so the conditions are identical. Regardless, my cages are all of the same design. All my temps are regulated at the same temp. all year by individual Helix Thermostats. I never change from a 14 day/10 night. I humidify my dragon room from December to April to account for the lower humidity in the winter.
I rarely post this type of information. Many far less experienced "experts" will dispute my methods and observations. Others will take it as gospel and figure that a sick 173 gram dragon is brumating when it is not. Also keep in mind that my husbandry is so exacting that dragons here grow at what can only be called a phenominal rate. I hatched a dragon 8/8/07 and he is 20 1/2" long and about 475 grams. Many would say he is an adult at that size, but he is not even 5 months old. He has exceeded both of his parents in length and will shortly exceed his fathers weight.
Given the choice, I would never allow my animals to brumate. They make the choice I am powerless to stop them and believe me I've tried.
