I am having a hard time convincing mine, even though I've said I'll take complete care of them, they will save factory chickens, and will make fresh, chemical-free eggs, saving money! I need some advice!
I didn't really have to convince my husband...he just laughed and said something about a "mid-life crisis." haha! What you need to do is get the other person (your spouse or your roommate) to list all the negatives. Then you counter each negative with a positive or neutralize it by explaining how you'll handle it. There can't be that many negatives. You've covered the most obvious ones...add that you'll keep on top of the cleaning, thereby eliminating most of the unpleasantness of living near chickens.
Honestly I am not sure how it happened. When I married DH and moved to his place in the country, I asked for chickens. He said no. That was it, no! Well one day about a year later he said, Lets go pick out some chickens! The next thing I knew he had built a "Chicken Palace". Now 1 year later we have twice the amount we started with and he has built me 2 incubators! We have 7 in the brooders and more in the bator!
Ask for something way bigger like a diamond ring or a Buffalo. Then tell him you will settle for chckens. If he loves eggs, then purchase some farm fresh eggs from someone local and make him some great eggs. Then tell him that is what he is missing.
