I have some crested ducks. and right after I ordered them I saw on here that they tend to have a lot of problems. Some neurological issues and that if they breed with one another the babies will die or be horribly deformed. I was just wondering whether or not any of this is true? because after I ordered them and was all excited and then I heard they had problems and I feel really bad and really stupid now. I mean I'm going to keep them and everything even if they do have develop problems. But so far they seem fine they're now almost two months old now and they play with all of my older ducks and act like all the older ducks so I don't know. So if anyone has/had crested ducks if they can let me know whether or not I'm a horrible person for adding to the demand of cute baby duckies with health problems I would really appreciate it...... oh and one more quick question, how often do you feed all your ducks? because I just do it every time the feeder is empty or almost empty. and I don't know whether or not that is a good thing or a bad thing or if it even matters either way.
