Anyone know what this is and if it is poisonous to chickens? This stuff has taken over our lawn, so there's not much grass

Looks like 'Lady's thumb' aka 'Smartweed' and is fine for chickens to eat...

@MeepBeep Thank you so much! In looking further, a popular chicken care blog listed this as one of the "good" weeds for chickens to forage on
