Hi- we are getting 5 sell ink pullets in a couple of weeks and I have used your site extensively in the past few weeks as we have been building our coop. ( my sister says that I have OCD- obsessive chicken disorder) . Our "free" chicken coop - a repurposing of my sons' tree house which fell during storm Nemo, is getting to be very time consuming and not crazy expensive, yet more expensive than we thought. Thanks to the forum we purchased 1/2 hardware cloth instead of chicken wire and also vinyl flooring. This weeks purchase- need to order metal roofing to cover part of their run. What is the absolute must have for my girls?
