So you're near Trellis Farm & Garden and Bob's Salt & Feed. (two feed stores). Both only have the basics, feed and feeders, not a real big range of chicken supplies, but still, they're nice stores. I'm maybe 10 miles further north.Welcome Mrs Weasley!
I am in West Chicago, about 10 miles north of you on Rte59. We are new from last year, but we have leanred a LOT since last spring... if you need help with anything please write back!
Garfiled Farm Museum is having a rare & historic breeds show May 19, including poultry. They're on Rt. 38 between Geneva and Elburn.
