I performed surgery on it but it didn't make it. I have a couple of really odd ones in the garden again that are similar to yours Lynn, and some similar to Twit's that got hail damage and is now growing odd. I know at least one of my weird ones is one that the critters kept digging up all the time so I'm sure that got damaged too.
I remember reading somewhere exactly what you said Jacki. Most crested types will have both normal and crested chicks.
