I've recently been helping a neighbor / tenant of ours sort out a stream going through our land & their garden that's become all clogged up with pond weed by clearing it with a rake. Now the ducks & geese used to swim through this stream & it leads into the river clun that also goes through our land so we wan't it to allow the water to flow better but we're stuck with loads of pond weed to dry out - can I give this to our poultry & waterfowl as they used to swim where there obviously was some x
