I've a Clan

A deer clan in my backyard. There are 5 or 6 of them & my backyard seems to be the be all to end all of hang outs. Here's 4 of them

While I'm fine with them needing to eat in my yard during the winter I'd prefer them to no spend all their free time here in the summer. Any tips short of a bear trap or a deer stand in the yard are welcome.
