Hi The Hogfather
Great news that hogs have returned there! I hope you get a tenant for the hog house soon. It would be lovely if it was used for a hog to give birth in.
Just one thing. It’s a good idea to leave water out all day every day, just in case a dehydrated hog ventures out during the daytime. Wide but shallow plant saucers are ideal and birds will likely make good use of them during the day as well.
Good luck and happy hog watching!
