Black Australorp- Hen or Roo

[butterthechicken]

I have 5 pullets who are about 16.5 weeks old. They all seemed to be hens for a while, but in the past week or so, one of my two black australorps has quickly started growing her comb and waddle and I have a feeling its not fully grown. She is a bit bigger than my other Australorp, but not too much. I haven’t heard her attempt to crow or anything. This is my first time owning chickens, so please be kind.

Pullet. She's more mature than the rest

Hen!

Definitely a female. The comb and wattles developed quickly because she is nearing the point where she'll start laying.

A lovely hen

She looks like a cute female chooky-chook to me!

Most of my chooks are the Hy-Line commercial hybrid breed. Some are bigger than others due to having traits from the different breeds that make up their genetics - to the point that some lay the standard tinted eggs and one lays huge creamy-coloured eggs! Also one is rather small (and cute), whose comb was quite small when she started laying eggs, and she also went broody after her first clutch.
However after the broodiness ended her comb grew big!

Our flock is also BLK AUS and it's a hen bird. One is a real bruiser compared to the others and isn't top bird. We got our first egg from one at seventeen wks and the others weren't far behind.
