White duck in Garden after Storm Ciara what to do?

Hi

I am after some advice with what to do with a white duck that appeared yesterday afternoon in our front garden during the Storm Ciara in the Padiham area in Lancashire. There is lodge nearby probably a couple hundred yards and a stream that runs off the lodge about 50 yards away. I am presuming it's come from the lodge or stream.

Fortunately we live on a hill so we haven't been affected by the floods, but the duck is still stood there this morning. it doesn't appeared injured but I don't want cats targeting it.

Please advise
