Not Asking anything just making a statement

None taken. You are not wrong that some Crested ducks can have issues. I never said they didn’t. A few have those bony protuberances and some get fat bodies trapped in their skulls when their hole closes which puts pressure on their brains and causes issues. But, careful breeding can minimize this. The trait is caused by a dominant allele (alleles are different versions of a gene). If a duckling gets two copies of the crested allele, one from mom and one from dad, they do not survive to hatch. That is what your Youtube girl and many others are complaining about. So, all crested ducks are thought to be heterozygous (one normal, one crested). But, if you cross a crested to a non crested, there is a fifty fifty chance of a crest and no homozygous dead ducklings in the shell. Here is a scientific article (the highest form of scientific information) about Crested ducks and proper breeding reducing neurological issues: https://pubmed.ncbi.nlm.nih.gov/18498950/ My other information did not just come from one book. But I used that other book as a resource to back my information.
Anyway, even though a few ducks can have issues, I do not think we should get rid of all of them. That was my point. Crested ducks have been around since before the 1600s and are portrayed in several old paintings. White crested are a breed which would become extinct. Instead, I think we need to be informed and choose the healthiest birds and do the right crosses. In the same way, quality breeders of pure bred dogs (such as Pugs) only breed the best, healthiest animals to hopefully prevent problems. @A boy with ducks , I just don't think this is an all or none issue. I never wanted to fight with you, only make you think and be informed. Sorry, I guess that is what bored high school teachers do in the summer.

Thank you I agree with you 100%

It's fascinating how many different dominant traits are dangerous/deadly in poultry. I know araucana are the same way with their tufts and Japanese are with their creeper legs, not to mention the frizzles and frazzles

STOP buying crested ducks. The little fluff on their head is a deformity that is literally a hole in their skull and will sometimes make them dizzy and fall over. I want to start a cult to ban breeding crested ducks if you didn’t know this and you have a crusted duck, I’m not trying to be mean, but I just think it’s dumb that people breed animals with deformities on purpose so let’s band breeding crested ducks
