Well hopefully this is the extent of his poor behavior,and he will stay on his own land.Do you have an enclosed run for the birds? Hard to set one up now with the frozen ground,but if there is a thaw anytime soon I would put something together.
Speedy healing for the hens,and lots of yummy treats.
NFH like yours just get worse everytime you push back.Not saying you shouldn't,but I am sure you know to expect more from him.If you have a fenced in yard I would post no trespass signs.I have heard you can not file trespass charges unless you are posted.The signs will make him mad though.I would lock the coop too.
Did your neighbor ever do a survey to disprove yours?Mine never did and still complains about the line. The land issue will make it impossible to live peacefully next to each other,because he will resent the loss of *his* land.And ofcourse after what he did to the hens I would despise the man regardless.
Hope you get those cameras up soon,and there is somewhat of a peaceful existence between the 2 of you. I know if it was a daily issue that stressed me and the family I would want to move...and hope I don't next to someone worse.Best wishes!
I told dh when our neighboring houses go up for sale we need to buy them.
