wild weeds

hi, sorry if this is in the wrong forum but i have these really tall weeds and then some little prickly ones on the ground (a LOT) and i was wondering if chicks are okay near these? i was observing them (4 week old gals) near the weeds earlier and i didn’t notice any issues with them pecking...

These two appear to grow exclusively in shaded areas under the Piñon trees. And these in the sunlight away from trees. Are any of these good for chickens?
