I built a shed coop this spring alone and with the help of my dad lifting the heavy stuff. i used a shed plan and that went well, now i'm building the run and i haven't found a plan that would suit me which is 8*10 with a lean to roof. I'm avoiding using 4*4 posts because i wont have the time to dig and its honestly so much work with other chores so the easy way was just 2*4s. i have checked online and gotten a few ideas. i can only get 3ft wide hardware cloth so i put the spacing at 3ft at centre. here is a picture of the frames, only 2 sides for now and i'm not sure if they will be strong enough to hold a roof and snow load, i have attached it to the coop which is pretty sturdy and will add in a 3rd wall and rafters on top for the roof. my ladies are here and its been so hot so they need this run up as soon as possible. woodworking experts please share advice.thank you
