Black Australorps. 5 weeks, do we have a Roo or Runt?

[hawcreek chicks]

Chicken newbies here. We have our first small flock. 2 EE and 2 BA. One of the Australorp's is at least 2x the size of the other, fully feathered while the other is still fuzzy. Do we have a Roo or a Runt?

Picks below.

Both of the Australorps look like cockerels to me. A lot of comb for so young.

It hard to see the little one. It could be stunted. I don't think the bigger one is a rooster. Watch for pink combs at that age, any pullets won't get pink until they are a bit older, they will stay a yellow orange.

I raise and breed both of these breeds and I'd say you've got all pullets. Black Australorp cockerels have dark pink to light red combs and wattles by 5 weeks of age. The pullet's combs and wattles will remain skin-tone to pale pink until maturity at 4 months.
