Well that was an interesting adventure. I was going to take some photos of my two chicks now they are about 5 weeks old to see if you all agreed with my boy girl guesses but my camera scared them and when I opened their little run gate one bolted in with the big girls. Good news is they all either ignored it totally even though it tried to hide below a couple or jumped away from it not sure what it was I think. Nobody tried to peck it which is pretty much what they were like with pepper last year, they just pecked her mum. So I might try putting them all together under supervision sooner than I had planned.
As for the photos, I took the wrong lens for a confined space where the chicks insist on cuddling up on your leg instead of moving far enough off they are in focus. Sigh.
So, I'll just have to explain
Suspected hen, "blAckie" has a little stumpy tail and has lost all those white baby feathers and is now totally black. This one is the most nervous.
The other whose name is in Korean and I forget sigh, has only a very minimal start of a tail, is behind getting its wing feathers and still has the white fluffy feathers on its chest. This one is very friendly and likes its tummy scratched. This is my suspected roo. Oh and it gave an alarm trill while I was in there because this scary bug flew past. They both dropped and froze
To be honest both their combs look much the same, maybe, the seconds could be a fraction bigger but then it's been bigger all over since it hatched though the other is quickly catching up. Neither has a pink comb.
I have read the Australian australorps can be sexed by tail and feather growth, the girls being the quicker to get both. Is that the same with yours?
