Hello, I’m from Australia and excited to be a part of your community.

I have 2 x 7 week old chicks that I would like help sexing please. They are australorp x isa brown.

Chick 1 - image 2411, 2412,

Chick 2 - image 2413, 2414, 2427

Also while I’m here, it’s currently winter where I live (10-15 Celsius day time, 0-5 deg Celsius night) so I still have the chicks in outdoor shed under heat. When would you remove heat and introduce to flock in main coop?

Thanks all!
Rooboy

Comb/wattle size on both says cockerel. On the black, pale enough to be slight chance is pullet. Colored one, the red on the shoulders is male specific color, but the breast color is female specific, so....gender ID: wait and observe.

Re: joining the others...as soon as you can make that happen. I try to raise chicks in the coop with the adults. (Heating pad/warm up station in the coop). I've found that the adults won't allow the babies outside if they feel it's too cold for them. I try to get the babies in the coop within the first week (and can see snow year round (very unusual)- it does get cool at night even in the summer). My flock ranges all day, from the moment I open the coop each morning. I have several roosters in this lot of ladies, and they all rotate which birds are on baby-sitting detail.
 
Hi all, thank you for your responses so far. I thought I'd add a few clearer photos to hopefully assist with sexing. If still too early to call I'll take more photos when they're 10+ weeks.

I should have mentioned we have 6 x adult hens and 1 x adult rooster already in the coop, so I want to know sex of these chicks before introducing them to the main coop in case they're both cockerels and cause problems with the rooster.

Cheers,
Rooboy.

hello, did my new photos help at all?
 
Thank you all I really appreciate it.

One last question: since the 7-week-old chicks are likely cockerels, should I avoid introducing them to the main coop, which currently houses one adult rooster and six adult hens? I'm trying to figure out a suitable place to keep them until they’re rehomed, as their current cage is getting quite cramped with how quickly they’re growing.

Rooboy.
 
All mine are in together from 12 weeks. I currently have 7 roosters, 6 of which will be on the chopping block very soon. They are starting to fight but mostly they get along
