Here is an Adult Description I was sent from April at H and H Poultry in Texas:
Adult Description
The most recognizable characteristics of Brabanters are the flat-sided upright crest with front feathers that are bent a little forward and their well developed muffs and beard, which form three lobes that cover the cheek and chin. The crest should not be as large of globular as the Polish varieties. The plumage is fairly hard and right, similar to Polish varieties. They have very large bodies: although, they are not heavy in bone. They have the appearance of strong, hardy birds. The shape of the body, which thickens considerably from the breast to stern, helps to determine that it is evidently a good layer since there is ample space in the region of the egg organs. The posterior part of the body is carried low, without the legs being short, and in the case of the hens, it almost touches the ground. The males have a moderately upright carriage of their body which is moderately narrower at the tail. The head is medium sized, rather broad between the eyes without a protuberance. They have a V-shaped comb consisting of two small, separated, rounded spikes placed in front of the crest. They have beaks that are medium in size, powerful and slightly curved. If wattles are present, they are very small and covered by the beard. The white ear lobes are small and concealed by the muffs. They eyes, which are prominent and alert, Are orange to red brown. The neck, which is fairly long, slightly curved and carried erect, has an abundance of hackle plumage. The back, which slopes downward, is fairly long. The breast that is carried a little forward is broad, full and rounded. The tail, which is carried at a 60-degree to 70-degree angle above horizontal, is large and well spread. The well-developed thighs are of medium length and set well apart. They have four toes on each foot that are well spread. The general characteristics of the female are similar to those of the mail, allowing for the natural sexual differences. All of the fairly tight, hard plumage of the Cream Brabanter is cream with each feather ending with a half-moon black spangle; however, the color of the tail may be entirely black. They have a horn beak and lead blue legs and feet.
