Weed ID please

[DesertTortoiseLove]

So today while feeding my torts I noticed these giant weeds with yellow flowers on them and some other kind of weed growing along the outside of the tortoises enclosure. Any ideas to what they are? And if they can eat these plants and the flower? All of these weeds are growing so fast we have hoed them and pulled them so many times it's hard to keep up with it all the time.

Ps. I have a mini field of foxtail plants growing that I have tried to get rid of again and again. Do you guys have any advice?

I may be wrong, but I THINK daisy-type plants are a do not feed. The very last picture is mallow, a good tortoise food.

Oh that's good to know that they can't eat daisies. Not even the flower on top? And for the mallow plant do you think I could try to plant it inside the enclosure to have them eat? Or just pluck leaves off of it and feed it to them? And thank you so much
