Heya there Jforestquail! .Guys this is our friend from Myshire's live...

I'd guess it's not so much to do with her age as it is her genes ...the pair's genes together.My current batch of buttons are popping! View attachment 2986141

My silver pair have started producing white chicks. I wonder if it is related to the hen aging?
I guess I was overthinking it. I've seen a lot of theirs hatch out over the past year, and maybe it just took this long for one to show up.I'd guess it's not so much to do with her age as it is her genes ...the pair's genes together.

Incompletely dominant means that it mostly overtakes the other genes, so a bird with one copy of the gene will look different than a bird with 2 copies. With the fawn (Italian) gene, 1 copy makes it italian patterned and 2 copies makes it manchurian. In silver, one copy makes it silver (dilutes blacks to silvers and grays) 2 copies makes a pure white bird that is often weaker and won’t thrive. In extended brown (without roux), 2 copies is Tibetan, one copy is rosetta. The incompletely dominant genes are what give us so much diversity. If an Italian is crossed to a pharaoh, you get what people often called speckled Italian, which is just Italian with a lot of spots, if you cross that bird to one that has one copy of Italian and one copy of range (often a rougher variegated pattern with indistinct spots blending into stripes), and you cross them, you can get the entire range of patterns offered by each one. You can get rosetta, speckled Italian, manchurian, and any other mix in between.When I was reading that info sheet on genetics, it seems that most of them are incomplete dominant. to my novice brain it pretty much translated to "anything can happen". lol
If you cross silver to silver, you have a 25% chance of a double silver (white) chick. Often these manifest as just eggs that don’t thrive, so you never knew you had doubles. But as your group ages and grow, is very possible that natural selection has weeded out some of the issues, and more are surviving. I started breeding my double silvers to purposely raise healthy ones because I want a group for meat, (they’re noticeably white meat).I guess I was overthinking it. I've seen a lot of theirs hatch out over the past year, and maybe it just took this long for one to show up.
