I really doubt the crest has changed shape because of the water fount. I've never had that happen. A crest just won't grow into it's full potential-- or show what it will look like until the bird is much older-- around 4-5 months you should have a very good idea of what it might look like. But even at that age, there will be a lot of pinfeathers and they can continue to change in shape and size. If you have lobes in your crest, there is something else going on-- usually because the bird has a vault. Although... the majority of my birds have a vault as well, and do not have lobes within the crest. What kind of water fount are you using? I'm using a typical 2 gallon metal fount for my birds right now. It doesn't seem to interfere with their crests. Can you take a picture of the crest you are talking about? Sometimes it's just going to be obvious that genetics are at play rather than a water fount. That would be the case when the lobe looks really pronounced and well defined. I don't have any birds with this problem, or I'd show you a picture. I remember having this discussion with someone else a while back and they were having problems with lobes within the crest. They had great pictures.
As a kid, my dad raised WCB Polish. This is a breed that has larger crests than silkies. They also have vaulted skulls. I showed them when I was a kid, but you will get some bad genetics where the crest just falls or separates. It's not anything to do with feeding/watering, etc... It's just a bad crest. A Polish with a crest that falls or separates-- well, you just don't breed them. So they have their own problems, too. But it reminds me a lot of silkies because you are working with similar crests and vaults. They either have a good crest, or they don't. You'd be amazed-- a bird with a good crest/good genetics-- it just won't matter if they get it wet, or what they do with it-- it will always bounce back. I have Polish right now that it's been raining and miserable out-- their crests are perfect. Then I have the birds that I would never in a million breed and they won't stay together and flop down. So I relate that a lot to silkies. And speaking of the rain and drizzle lately-- my silkies have gotten drenched a few times in the last couple of weeks. Their crests were flat against their heads when I brought them in. I didn't do anything with them, but put them up. The next morning-- they were all fluffed up like nothing had happened without me having to do anything for them.
She looks very nice. Are you wanting to show or breed her? Is she a Black or a Blue? The majority of my blues I got this year are all this dark. Makes it very tough not to call them black when I know very well they are blue. LOL!
