I would say it is to be more self-sufficient also. I mean, even though my girls are pets, I know that if really hard times hit, we COULD use them as food--but I'd cry.
As an artist, they have always been an interesting subject and personally, they are pretty comical. When I was given my two little silkey pullets, I was have enormous stress at work and they sure helped me to forget about work day. All my coworkers (well, nearly all) got a kick out of hearing about their antics and pecking order dramas. After my job was eliminated, I began a monthly "Coop Newsletter' so my ex-coworkers could continue to get the 'scoop in the coop'. It is still going and can be reached by the View My BYC Page link to the left. They are still a great stress reliever--I have found that even after (forced by finances) retirement, I can get stress! ha! The eggs are just gifts since all my girls are basically considered exotics and looking after them gives my days some structure. I am grateful to have them and am planning to move to somewhere I can have more and maybe sell eggs at a farmers market.
