Wow ... I saw this thread but didn't want to open it ... I was afraid I wasn't up for someone else's heartbreak.
I'm so sorry to hear that you are going through all of this.
I'm torn as to what to say. Part of me says that, I know you love your guineas and it is WRONG WRONG WRONG what your neighbors have done ... but ... if it is going to further compromise your health to have to deal with this, it seems like they are just stealing your health AND your guineas.
Then again, I don't know if you wouldn't still be stressed even if you decide to let it go.
Sigh ... I am just so sorry you have to go through this. I think I remember your posts about the dogs coming onto your property and you having to kill one. Having to live next to people like that ... that is very stressful 24/7.
It seems that the law enforcement should be made to do what they are supposed to do, if you do decide to pursue this. Have you asked them to SHOW you where it says that poultry aren't being kept if the pen is open on top? I mean, written in the code? If not, then it seems you are in the right. Maybe if you ask them that, and let them know you intend to pursue it with someone with more authority, they will pay more attention to the details of the law? (Though I know I'm late with this, if they actually DO have them in the house now.)
Anyway ... I am so thankful for the person who came through for you. As long as we live on this earth, I know we will run into people like your neighbors. I'm just thankful that there are others who aren't like that, who are wonderful people and who brighten our lives.
Prayers are with you!
