They don't understand color genetics, which is obvious from their most recent Facebook post... Cremello isn't a gene, it is being homozygous for cream (2 copies of cream and will pass 1 copy to every foal) and on a chestnut/sorrel base. Perlino is also homozygous cream but on a bay based horse. Smokey cream is also homozygous cream but on a black based horse.
To get a buckskin, you need 3 ingredients: at least one black gene, at least one agouti gene and only 1 cream gene. Mix well and you get a buckskin
Your mare is sorrel/chestnut (homozygous red, chestnut and sorrel are genetically the same) and carries no black (black is dominant and does not hide) but may carry agouti which hides on red based horses because it only modifies the black gene (making black horses bay or brown instead of black).
If this cremello stallion has produced buckskin foals with sorrel/chestnut mares, he is perlino not cremello. If his owners tell you that you have a 10% chance of a buckskin foal, they clearly don't understand genetics. A cremello bred to a sorrel will produce a palomino 100% of the time. If he was color tested and the owners got back the results that he is truely a cremello with an agouti gene, the only way he could get a buckskin foal is if he is bred to a mare that threw in a black gene.
Sorry you lost excitement by sharing the news, but don't let that keep you away. This is an open forum with many horse lovers with all kinds of experience, education and background. Some things that are said are opinion and/or experience based while other posts are for your education as an aid to help you grow and learn. No one can stop you from breeding, but it is a highly debated topic. We all want to share our love of horses, and sometimes certain topics (like breeding) can bring out the worst. Breeding is dangerous, when things go wrong, they go very wrong and there may be little to nothing you can do to prevent the loss of either mare or foal, sometimes both mare and foal are lost. There are things to consider in choosing a stallion, his strengths need to build on your mare's weaknesses and vise versa because no horse is without flaws and we want to better our odds in the breeding gamble. When breeding 2 horses with the same weaknesses, you are duplicating weaknesses instead of trying to make improvements. Read and learn, discover and explore, listen and then chose what you want to gain from your experience.
