I love the idea of another pop door and I have the space to install another one opposite the existing one--there's room for another run and everything. When I mentioned this to my husband last week, he gave me "the look", haha. So, maybe next year!
I'd like to keep all the supplies in here, too. I'm thinking galvanized trash cans w lids. There are a couple different sizes I want for feed, shavings, DE, etc. I know if I build a shelf to put them under the hens will poop all over it, and if I don't build a shelf they'll poop all over the cans. We have space in another shed in another part of the yard (we're on about 1/2 an acre) but I'd like to keep all the chicken stuff together.
Where do you store all your supplies?
