hi, yeah i appreciate what you are saying, i wasnt talking about heterozygous coloured stallions though just coloured stallions in general, im no expert its just i was talking to a breeder at addington last week and they were telling me that alot of breeders wont use grey mares with the coloured stallion as theres even less chance of a coloured foal than with say a bay mare or chestnut. prehaps they were passing on incorrect information

Yep! A heterozygous coloured stallion has a 50% chance of producing a coloured foal to a non-coloured mare of ANY colour including grey. If the grey mare is heterozygous for grey, then there's a 50% chance that a coloured foal will grey out.
So they were right in ONE way - because while your chance of a coloured foal from a grey mare is exactly the same as from a bay or a chestnut mare (50%) your chance of having a foal that STAYS coloured from a grey mare is only 25%.
