This is so funny and comforting to hear a lot of other ladies' husbands think they're crazy, too. My husband says exactly the same kinds of things. He finally confessed that he was impressed with the chicken condo I built by myself with assistance from my young sons who volunteered to help out with holding pieces while I hammered.
My sons and I are all into the two Dominiques we have (Mr. and Mrs. Chicken) who share the condo, and now the five Buckeye chicks we just hatched this past weekend. I think my husband just doesn't realize how very easy chickens are to raise and how much they add value to our lives. He'll come around, I'm sure. How could he not?
Enjoy your chickens! It will be a barrel of fun from now on, I'm sure.
