Ghosts AND birds, in the same story. The house I live in now was built by a couple in the 1950's and they raised their kids here. It is surrounded by family owned lands, and all of my neighbors are related to these folks although I am not. Before I started keeping chickens and quail, I had trouble with "grandma", who died here in the house, from time to time -- things would fly off counters and break, etc. if her grandson didn't come by (he's my neighbor) and visit often enough. He still keeps up my yard and does any heavy work I need done.
When I first started keeping birds I was hatching some quail. I had one left in the hatcher, and some in the brooder. Before I left, I checked on them all. Then I went away for a few hours. When I got back, the lone quail from the hatcher was in the brooder with the rest! I asked my neighbor if he had come over and moved it -- he said no, and said, "It must have been grandma!" The occurence made their family feel good that she was still around. "Grandma" kept and enjoyed chickens during her long life. I guess now that I have them here, she has more to do, and doesn't need to break dishes to get attention anymore.
I'm glad she's watching over my birds.
