There may not be such a thing as a "perfect Neighbor," but it sure sounds like you've come up with a "Perfect Solution!" Please let us know how everything turns out.@MROO I have made the decision. I am going down the lane to speak with him now. There is an old dilapidated shack on his land. I have some old wood pallets and left over hardware cloth. I will offer to help him make this shack into a secure shelter so the birds will have somewhere to roost at night. I won't be able to do this work on my own, I'm relying on his help. If he agrees to my suggestion and helps me to make his shack secure I'll give him the eggs. If however for whatever reason he doesn't help me with the renovations, I'll tell him about me seeing chickens more as pets than livestock, and help him find other fertilised eggs. I know another neighbour on our lane also has fertilised eggs, as his birds hatch out chicks every year. His birds are the typical small chickens that are seen foraging on farmland all over this area in Spain. They are very flighty and quick and they seem to be exceptional foragers. I'm sure eggs from these birds would be more suitable for him.
I believe I could live with this decision.
I would like to thank everyone so much for your input. It was a very lively thread with many differing, and very interesting opinions. It has widened my worldview, and I am very appreciative, especially to @Shadrach, and @Stiletto , (And @Shamo Hybrid - for your wonderful humour! I still get a chuckle out of your post when I think of it.)
