I like Backyard Poultry Mag, too. I subscribed to it last fall, before I got chickens (mid-summer). I just resubscribed for 1 year. Some people on here (BYC) say that after you have had poultry for a while, that the magazine is not as useful. I can see that being true, which is why I subscribed for a year instead of for 2 years.
I also like to switch which magazines I subscribe to. I only subscribe to 2-3 at a time, and so I rotate as my interests change. When I first got my house (c.1855) - This Old House. I tried Countryside on the advice of a friend but I didn't really like it. Now, Backyard Poultry. Next year, ? I might look for something related to permaculture, or maybe give Home Power magazine another try (they have grown up a lot since I subscribed back in the mid 90s).
