Farmed deer are farmed just like cattle: They recieve supplementary feeding for production purposes, their breeding can be managed, they can be housed in winter, de-antlered, calves can be weaned, they can be handled through a crush, they have eartags, they get medication from time to time, and must be slaughtered in an abattoir.What's different, they aren't wild they are fenced in and slaughtered to sell = farmed.
Park deer, although enclosed, live pretty much as a wild herd: They are not handled in any way, recieve no supplementary feeding (except for welfare reasons), are not medicated or de-antlered, their breeding is not artificially controlled in any way and the youngsters are not forcibly weaned. They are not housed in the winter, they are legally wild, and are not required to be eartagged. Furthermore, they must be killed by hunting (as per wild deer) and not slaughtered.
