No one said this is the only item to be fed. I believe, no I know, I said that exact, that it's not the only thing to be fed. I also know I mentioned orchard hay as the best to feed Weeds etc in hay is not a bad thing as long as they are safe. Most likely they are, as if it's safe for a horse or cow to eat, it's likely safe for tortoises.Like you said not alone. I have yet to see a tort eat hay with nothing else and be healthy. I have yet to see a tort eat what is needed if fed hay. Stalks, Stems there is alot that they will not eat. There is only some they will eat. Again in my infancy of tort care but not a fan of HAY. On farms hay is given as a end all food, not as a part of a complete diet.
Not sure how many Feed Stores there are in Chicago but here they're every where. You can go to 2 feed stores a block apart and buy a bail of hay. The 2 bails will be quite different in content. EXAMPLE: The last 2 or 3 cuts on an Alfalfa field will be higher in "WEEDS" than Alfalfa. As other Grasses (Weeds) start to grow within the field they are cut and bailed as well as the Alfalfa.
Just take it as you learned something knew today and take advantage of it. No need to feel offended that you didn't know. That's how we learn. We are all wrong at some point, more than once.
