Hi DerkeLThomas
Sounds like you have been very industrious! I’m sure the hogs will appreciate them. You are lucky there have been visitors already – sometimes they don’t take to them until they become ‘part of the furniture’.
Ideally you would site a feeding station away from a box you hope to be used for nesting. That is partly so as not to attract predators to a nest site, but also to avoid ‘rowdy’ males potentially being outside a birthing nest – that sort of thing.
Glad to hear the hogs have made good use of the water provided.
Good luck and happy hog watching!
