Meat, fat, skin, feathers and SKULL. A defect according to the standard is "head too small and narrow". The "brow" or "beetle brow" as many refer to it, usually improves with age. A good high protien diet helps. It is usually evident at an early age in high quality birds. It is really a distinguishing characteristic of the Brahma breed. In my personal opinion, narrow, sparrow headed birds should not be bred from. Opinion again, a good head is the first thing to catch a judges eye.
Tim, you explained it just right. Lots of new Brahma folks believe the Brow is mostly bone, when in all actuality it is mostly the other items you mentioned. You are right Broad Head, Broad Chest and broad Back and a lot less problems. The back should be wide alway back. Don
Hi - lurking and learning. How high of a protein are we talking? And from what age? I usually throw in a bag or two of 20-22% a couple of months before show season, and when everyone's molting. I give treats with higher protein here and there, because I have all heritage birds, dual purpose and meat breeds, including giants and faverolles. I'm on a list for a couple of LF brahmas I hope to get later this spring. I just hatched out some bantam cornish - a new breed for me. So, how much protein, from what age, and for how long a duration?
Also, are you saying that what contributes to the brow is able to be manipulated by diet? It's not just lucky genetics?
Thanks! I've started a Brahma doc. and copy and paste any "lessons" from here for my own files.
PS - I use the Frontline/Q-Tip method as well. Works great for me. I know a couple who have over 200 crested birds and they never have issues.
