Need advice for the best vines and plants for in a chicken run!

In general, I agree that it is difficult to get things to grow in a run, especially if you want them to.
I cut two-three inch diameter limbs off of a black willow and used them as horizontal uprights for my hens' run roost bars. The area of our run is somewhat damp, like our area in general, and those branches, despite sitting in the open for weeks before placement, apparently rooted. Those branches have leafed out each of the past three years. The girls eat the leaves that they can get to, but against ALL odds (including having absolutely no roots to begin with), those willows continue to live inside the run. We will be trimming them this summer!

An allergy is very different from "this food causes kidney damage in this animal (in x amounts)"
I tried to look up what you said earlier about fox terriers being able to eat grapes before replying, and literally nothing came up no matter how I changed the wording.

Whatever "list" he has... is questionable when there's no way to back it up with facts.

This will come across as me targeting a vet you trust, I'm aware of that.

But this is very concerning to put on the internet as "fact"...

Yes! Please look up the potential long-term damage to dogs that can be caused by feeding grapes, raisins, etc. We had to eliminate our grapevines that were fenced away from our dogs because the birds kept dropping the grapes where the dogs could get them. I'm not willing to take a chance on making our pets ill if I can help it. I also don't give them chocolate. From what I have researched it is the dark baking chocolate that causes the most damage. Milk chocolate may possibly just give them diarrhea depending on the quantity eaten. Our dogs vary in size from 7 to 22 pounds. We recently lost our 17 year old pup to old age and declining kidneys. I want them all to live just as long!
