I stumbled upon the maggot feeding of chickens from carcasses technique last year and was fascinated, so did a little reading on it. My overall impression from that reading was that this is a very cheap/free source of protein that will occasionally result in botulism toxicity of all or some chickens. I live on roadkill alley so it appealed to me in that it could provide some use for the many roadkilled animals that I see. The people who use the technique regularly seem to describe clinical botulism in their poultry as rare. So, I think that using it depends on your goals and comfort with risk. I myself couldn’t quite see myself picking up the roadkill or tolerating the risk, so I haven’t tried it.
I’d you are interested, there is a lot of info available on the maggot feeding technique on the web, especially from more pragmatically minded Permaculture oriented websites and blogs. For example:

It was also discussed previously on BYC, with a focus on the possibility of botulism
