I'm sorry that a new member arrived and kinda got beat back for what I'm sure was a request for information and perhaps some empathy for the situation.
With that said, I can tell you I didn't even move my two wiener dogs or any of my chickens to my new property until I got the fence installed. The next door neighbor has dogs, and one is a little chihuahua mix which can squeeze through the original fence between our two properties. Makes my dogs nuts. Bella is a cutie and doesn't chase my chickens, just wants to bark at my wiener dogs. They bark back. I put Bella back over the fence every now and then.
My chickens went through that fence occasionally and their very friendly lab mix killed one. She ran, Ace ran after her, cornered her, and "played with her" too roughly.
My chicken out, my fault. Those neighbors were mortified, wanted to pay for the hen, I refused the money and reassured them it was not Ace's fault - that hen had been on HIS territory. What I did do was put up some chicken wire along that fence, to keep my chickens in, and look: it keeps Bella on their side of the fence, too! When I had my fence installed, it was around the open property line with very good fencing; I left the not so great stuff up between the two properties. Next year I will replace it with the same stuff I put up around the rest of my land.
If my wiener dogs got out, I would be devastated, because I know someone might shoot them. I know this. Hence the fence completely around my two-thirds of an acre.
My neighbor on the OTHER side shot - with a pellet gun - one of two dogs roaming as they were checking out my chickens ranging freely in the yard. Both dogs had been around more than once and one of them was right up aginst the fence, starting to dig. Neighbor pumped up his pellet rifle for a "good 5-pump sting" and plonked the dog in the butt. Yipe!! And both dogs took off. Then he called me and suggested I get a gun of my own. He and his wife are retired and home every day; i am off my property 13 hours every week day.
I was impressed he felt compelled to be worried about my chickens.
Please do keep your dogs on your property.
