((((Open Eyes)))
And now, gently asking questions because I can feel your pain through your words here...
Is there any way you take a one-week break to try to relax and clear your mind so you can come up with the best plan to follow? I totally understand how anger can so totally blind us from being able to see any answers. And I believe you have every right to fight and win this case.
Could you install a security camera and/or a light connected to an alarm to alert you when the dogs and hens enter your property?
Are you calling the police each and every time that the trespassing occurs?
Is there someone higher in the court system that you could appeal to for help?
And I do agree with what Byz wrote - most particularly suggestion #4.
Oh - and good for you for writing this all here at PC. I hope even doing that helps relieve some of your stress and I hope other members will be kind and supportive as you continue to battle through this.
