Looks like wood sorrel. I have allowed mine to eat it in moderation from time to time but do pull it from his pen since it’s so high in oxalic acid which forms stones.
That might be black medic. When it grew in my horse pasture the horses ate around it, not eating it. "They" say it's safe for tortosies to eat, but I'll bet they won't eat it either. But black medic usually has little ball-like flowers almost right away, and your picture doesn't show any flowers. So?????Hi, these weeds are growing in my Marginated tortoise pen are they safe for him to eat? View attachment 247310View attachment 247311
