That's a big comb for 4 weeks. I would tentatively say cockerel. If it turns bright red in the next 2 weeks, and the wattles follow suit, definitely cockerel.
Thanks for the input. I’ve been really watching the comb because it does seem to be big, but so far has remained a neutral
color. I keep crossing my fingers for a hen, but I’m worried it might be a rooster as well.
