I know there aren't a lot of people on BYC that have Black Sumatra(and information on them is pretty scarce), but I have a couple of questions about them. 1. Do they tend to be relatively slow to mature? My rooster is 5 months old and has not even attempted to crow. 2. At what age do the roosters begin to develop spurs? Not even an indication of a spur on my boy(I guess I thought with multiple spurs they would begin to develop at an early age). 3. My rooster does not seem the least bit interested in "romance" at 5 months old-is that normal? 4. At what age do the hens begin laying? I may be guilty of comparing my little Sumatra rooster to my giant SLW rooster Maynard(same age as Sumatra roo) who stomps around the property like Godzilla crowing at the top of his lungs and chasing the ladies(much to their dismay). Any help(even guesses are better than what I know about this) would be very much appreciated. For anyone who is interested in the Sumatras, they are incredibly sweet little things. I adore my pair.
