how often do chestnut foals change colour ?

[mariond]

My mare foaled last night and produced a chestnut filly which came as a bit of a suprised as she has no chestnut in 2 generations of her breeding (she is a dark bay with 2 bay parents and a grey grandsire) Having checked with the stallion owners this morning I find that the stallion only has bay and coloured in his breeding. Is there a chance that she will turn grey ? The previous foal was coloured but I knew that that was just luck but expected a bay not a chestnut if solid colour. Shes lovely anyway but I just wondered. Many thanks

One of the parents has to be grey to get a grey foal.
Chestnut is recessive and can pop up from nowhere unless mare or stallion are true breeding bays ie unable to produce a chestnut foal.
You would probably have to test for that though.
What colour was stallion

The stallion was piebald

Our little baby who was born 7 days ago was born chestnut, but by the following morning we could see that she was going to be grey. She has loads and loads of grey flecks in her coat, and they are getting stronger every day......however her Mother is grey so this was the colour we expected.

I don't expect your little one will change colour; but then I am not very good on colour genetics......Druid is your woman!!

Oh and huge congratulations!!!

my horse had a grey dam and the stallion was chesnut. he was born a chesnut and turned grey.

George had a grey dam and bay sire and was born chestnut. He still has sort of roany patches, and when we bought him the bottom half of his tail was chestnut!

You have to have one grey parent to get a grey, I'd say you have a chestnut, your mare must have carry the chestnut gene because its recessive it can skip generations unnoticed so to speak. As the dad is piebald this means he is either Black carrying Chestnut with the Tobiano gene or Homozygous Black carrying the Tobiano gene, its the only way to get a black and white (piebald) as black is also recessive but not as recessive has chestnut, so to have black you must have black/chestnut or black/black, so has you have a chestnut foal the dad must be black carrying chestnut with the Tobiano gene. This is how I understand it. If you got through that, you need a medal.

My boy was born chestnut and had a really cute little blonde perm between his ears! It was even on his passport that he was chestnut, but that had to be crossed out when he changed to a bright bay!
