So from my second set of eggs 18 hatched. 6 were black australorp and 12 were blue australorp. If you add those to the first set of chicks we have 11 black and 12 blue, which is very close to a 50% split.
The picture shows my lightest blue, my darkest blue and one black, just for fun.
Those look like roos to me. They are difficult to sex when they are young. You have to vent sex them, which is difficult. Otherwise, you have to wait to see that red comb and wattles on a chick younger than 10 weeks.
Oddly, I just had a similar situation. Out of 8 eggs from a blue australorp roo and black australorp hen I got 2 that didn't hatch, 5 black chicks and one blue that died soon after hatching. I was wondering if there was a defect possibly linked to the blue gene.
I have 21 more due to hatch...
I'm actually hoping that these are both roosters. I have a flock of black australorps and I would love if these were both roosters.
I think they are, but I'm questioning the one on the right.
What are your opinions?
5.5 weeks
They look like females to me too.
The best explanation I've heard for sexing black australorp is seeing bright red combs or waddles before 10 weeks means rooster. All the combs I can see look the same shade of pink.
Do you think that is a rose comb?
Edit to add...
If it is a rose comb it could be a 'black rose comb' really nice looking bantam with white earlobes. Sold at my pet chicken.
