I am sure the guy is speaking in terms of farm animals such as cows, chickens, pigs, that sort of animal
kwim? Who would buy an incinerator for deer or mice, when there are less expensive way to deter or get rid of them, just wondering? Most people don't see an issue with deer as they do not tend to stay in one location and will move about freely. And especially on someone's property as they are very timid animals and tend to run away at the sight of humans. Any other pesky, small animal; rabbits, skunks, raccoons, rats, fox, wolves, gophers, ect. same thing, easy to take care of without the use of an expensive incinerator. The FACT DM did not live on the farmland (probably rarely visited), is a good indication he was not aware of pesky critters there
kwim.
I am certain should DM have had 'issues' with deer, during hunting season would be the time to take care of them and he could have made profit from them instead of incinerating them. Many people would love nothing more than to take a deer off of his hands for a delicious venison steak or burger. HTH. BTW it is against the law to hunt deer out of season, you must have a deer hunting license and there is a limit to how many deer one person can kill. HTH.
