Mummy duck

Or is it. I dont know they are always 2 nearby the chicks protecting them. I guess they could both be mum's to the chicks. But i think one just helps out or by instict sence it lost its own protects them. Either way they seem to have accepted me and doesnt give any kind of worrying signs when i go near them. Bit funny if i look at a direction the ducks try to look that way too now, if i move away like for people walking by they move away from the road a bit too untill i go back. Bit funny.
