I believe it but.....15 years ago when I was on the market for a house, I spent weeks or maybe even months looking at all of the available listings in the area I wanted to buy. Finally one Sunday I went to an open house for which the house was so-so, but then I stepped out into the backyard. Sitting in a corner of the yard was the most beautiful chicken coop I had ever seen, and enclosed in the run were 6-8 chickens. I decided right then and there that this was the house for me. Having grown up keeping poultry, I was eager to get my own flock as a young married woman, but the thought of building a chicken coop was daunting. We made an offer on the house that day and a condition of the offer was that the chicken coop stayed and at least two hens as well! The seller gladly accepted our offer and left 2-3 pullets who started laying almost immediately. I never did fall in love with the house but I loved the chicken coop for as long as we were there
So it could be that a potential buyer might feel the same way I did and be more interested in the house BECAUSE of the coop? (Just recently DH and I discussed moving to a property with more acreage and I took a look around our area to see what is available. The only two properties that really jumped out at me did so because they already had some outbuildings - including chicken coops).
