We called Animal Control, the Zoning board, and the county extension office before we even looked at the 1st coop design. We spent a whole lotta money making the coop look nice so that it woudln't be an eyesore in the neighborhood, as well.
We talked to all of our neighbors before we got the chickens and everyone was fine with it. His wife knew months before we got them so I assumed he knew as well. When we got the chickens he raised sand, but decided that we could keep the chickens because his wife told him to drop it.
Now, that "we could keep" bugged us, honestly. We decided that since we knew legally we could have the chickens that he would have to do the research himself.
Should we present what we've found to him? Or should we just let him figure it out himself since he wants to be so neighborly?
Thanks for the advise about documenting. Now that the sun is up well I will start taking pics. If any poison gets on my property, I'll know it and I'm sure there is something I can do about that.
Yes, there are 3 small children in the area - two are mine and one is his.
I would never let my chickens onto his property anyway, because that would just be irresponsible on my part and I'm not one of those neighbors.
