I have 5 blrw chicks that are just over 4 wks old. They all feathered in quickly, with long tails. I have 4 slw as well, but I'm fairly certain 2 of them are pullets and 2 cockerels. The slw cockerels feathered in slowly and had very short tails. The 5 blrw all feathered at the same rate as the 2 slw pullets. But then combs started turning red on the blrw. There are no signs of wattles yet although its probably too soon. Are there any tips on what to look for at ths age to distinguish cockeral from pullets in blrw? I don't have any pictures right now but will try to get some later.
