So the word is spreading more and more. I owe a much of that to the local media. I didn't even have to contact them, they've all contacted me and that's a blessing because I'm certainly not an extroverted personality so this aspect has been very helpful.
Yesterday, the Iowa City Press-Citizen printed an opinion article that favored urban chickens and an Iowa City resident, Eric Johnson wrote an opinion letter also in support of chickens in our city. This is so wonderful, I love to see our community coming together like this.
Again, I want to urge people who are interested in raising urban chickens (or just want the right to do so if they choose) to contact city council. You can call our council members, write a letter or send an email. The more correspondence they receive from Iowa City residents (in addition to the petition), the greater our chances of getting chickens allowed in town.
It seems at this point the next steps are strategic ones. I've received several emails from interested residents who are anxious to have an organized effort. Organization is my friend, but I've never organized this type of effort so I'm turning to some pros for pointers and doing lots of research. I'm also adding new links to my sidebar for reference.
