Can you explain what you mean by that statement above?I think that floppy leghorn comb is a mistake, IMHO. Especially in the whites. A smaller comb looks better on the hens.
The English standard can be found HERE and the most resent draft for the proposed APA standard HERE.
My interpretation is that the hen is NOT required to have a floppy comb but that it is one of the sexual difference that is allowed in the female where as the the English standard lists that a twisted or folded over comb is a serious defect in the male (i.e. allowed but something that will be docked points in exhibition and should be worked away from in breeding).
Are you reading something fro the English Standard or latest draft of the proposed APA standard? Please post what you are reading so it can be discussed and if the consensus is that it is listed wrong or confusing it can be revised.
