Frisian Duck - ready soon?

This is my first time with Frisian duck and I absolutely love it. The seed has the best genes not to mention being major inconspicuous. My question is the weather is drastically changing over here and getting really cold at night anyone have any idea how much longer approximately it needs? I would like to give it one more week but I'm afraid it might need two?

I'm not used to purple strains so I'm not as good as you identifying the usual signs..
