South Central New Mexico-what weeds to avoid for chickens?

[ChickensInNM]

They aren't free-range, but weeds grow, especially after rain. What weeds should I watch out for especially? We get a lot of pig weed where I live. I know humans can eat it, but can chickens? I pick fresh grass for them. They eat some of it, and the rest makes great bedding. No pesticides or herbicides involved, at all.
