In regards to roses and chickens, I thought I read somewhere on here that chickens don't like to eat roses or rose bushes to be precise...I thought about planting one inside the run but maybe now it will be on the outside but still close enough to keep it looking pretty. (not sure if they appreciate pretty or not but I do!
I have two very barren rosebushes in the backyard where my chickens free range. I've even seen them eating the petals.
