Backyard Chickens did a good job of summing up what we have so far. I'd just like to add that, as I read over those ideas, it occurs to me also that there are two possible fliers or handouts here: one that would go to prospective chicken owners to provide them the information they need to properly care for and "save a chick," and another targeted to store owners to convince them to hand out the fliers to their customers.
I know that two fliers sounds perhaps unnecessary, but since we've really got two different audiences here with two very different goals, we might have more success targeting them separately. For example, for store owners we might be able to provide ideas about how to track additional sales generated from the "Save a Chick" campaign, but customers would not need to see that information, and it might even turn them off. The flier targeted to store owners/managers would frankly not need many copies, and (in contrast to something targeted at customers) it might be possible forgo printing the store owner flier professionally provided we have volunteers at the forum willing to print out a handful each (5 or 10?) to take to their local stores. The stores that agree to distribute the fliers to customers could then be provided with a supply of the fliers for customers/consumers.
Nifty Chicken, I love your idea about using the BYC forum to keep the files. What if we made the fliers downloadable pdfs so stores could print out additional fliers for their customers if they ran out? If we decide to do that, we may want to make both a color and a black and white version so it would be easy and inexpensive for them to do (and for us, too, for that matter).
What does everyone think about having a contest, similar to the bumper sticker contest, in which we could design and submit a flier?
