It's one of the Aster Family species. Some of them are difficult to distinguish at that age, but I will say Annual Fleabane or Daisy Fleabane.
I've seen them browsed some at that stage of growth, but around here they are left alone once they get bigger. In an area short on food I would expect them to continue to be browsed as they mature.
PS: It would also be good to post your USDA zone and state in your profile. That can sometimes help with plant ID. Thanks!
