First off, I'll say that I am pretty sure that we all can agree that no bird of any breed or gender should be crow headed.
When it comes to the head of a sumatra as stated per the SOP (at least my 2010 edition) it says
Head- short, round
Beak- short, stout, well curved
Where does the "big" come from? From the pictures posted and from what was written, one might think that we should be breeding sumatras with a cornish head, for which the cornish SOP reads
Head- moderately large, short, deep and broad, indicating great vigor, skull flat, broader at front than rear......
Beak- short, very stout, well curved
Since there is no size reference in the SOP of the sumatra's head (Examples- big, small, narrow, broad). Unless one uses short as a size, but then this normally is interpreted as not big. Why is the biggest head and shortest beak possible the best? As I see it, when you increase the head size, to keep the head in proportions with the body (so the head doesn't look like a big ole rock head) one must increase the size of the bird's body. With a bigger body comes a heavier body weight, and SOP listed weight for sumatras are 5 lbs for a cock and 4 lbs for a hen and dq-able once the bird is over the 20% mark (6 lbs for a cock).
I think a round head that is broad but short (from the point where the beak meets the head to the back of head or top to bottom of head) with a beak that's short, stout, and well curved (but doesn't instantly put someone in the mind of a cornish head) is more of what the SOP is after.
So I ask where does the biggest round head with the shortest beak possible (that puts at least me in the mind set of a cornish) come from?
I am not trying to be confrontational and hope that its not taken that way, I am just trying to figure out where the big heads come from. Thanks for any input on this matter.
