One drake should be fine if you really want him. If you are thinking of breeding the WH, you will end up with more drakes to either cull/rehome so ask yourself if you can do that. If you aren't thinking of breeding the WH, then just ask yourself why you really want him. If you have a good solid reason, then one drake should be fine. If not, zero is even better.
Thanks for the help!
I guess I mostly just want him because I think the WH are gorgeous and also because I thought males were quieter and wanted one quiet duck? But that doesn't really make sense because with all girls, one male wouldn't really make a difference in volume unless I got all males.
So I guess it would be best to not get one?
But I don't have a problem with rehoming although I might get too attached to cull. And they might be hard to find homes for or not really? Might be harder with mix ducks than purebreds?
. But if you do hatch ducks, they are 50% likely to be male so you will most likely be in a cull/rehome situation. Girl ducks will produce eggs without a drake around so if you aren't breeding, the only advantage with the drake is the pretty green head. I got my first drake because of the pretty green head. I got my second drake because as a crested duck, it would be in additional danger because I have a drake who would tug hard on the crest if my crested was a girl. So I had a reason for both of my boys. When I have to deal with the additional work and worry - I can look at those reasons and know why I did it. I love both of my boys and would never get rid of them, but if I could time travel, I would probably not have gotten my first drake, but would still want Tevye (not any crested drake, just Tevye), because despite being a drake, he is totally awesome!
Each duck's egg looks slightly different. Some are longer vs wide and different weight ranges some ducks have smoother shells, some are coarser. Other ducks may have different color eggs depending on what you get. WH are white, but with just a few ducks, you should with time be able to identify who's is who's especially if you only care about 1 duck's egg. I know a couple of my ducks' eggs by sight but most of the white ones, I can't identify - Entie's are white though and I can Identify them because they are almost perfectly round (at least for an egg). Dove's I can identify because they are green (I have three green layers) and they have a ring that is slightly bluer around the pointy end (no one else does that). Allie's are over 90g, no one else is. Tella and Ettie - actual sisters born the same day from the same nest have tangerine tinted eggs (but I can't tell them apart.) If once they were laying you brought your WH inside for a couple days, you would know what her eggs looked like. If they were identifiable vs the other ducks, you could go by that. If not then you could isolate her long enough for a brood of eggs (after making sure her eggs were fertilized) then hatch those eggs.
