I have 2 BLR wyandottes. Their combs are very different. 5 weeks. No redness or wattles in either.
Chick 1:
Chick 2:
I also have an australorp. 4 weeks old. Acts very pullet-like, but this comb and wattles has me worried. Haven't had an australorp chick before.
HI! If you could please post a side view of first 2...australorp looks like a young cockerel
