4 weeks old Black Australorps

You could just start bringing that one in at night as soon as you get worried. If you're willing to do it every night until the chick is 18 weeks, then starting a little early isn't likely to make a big difference.

And even if the chick turns out to be a pullet, bringing it in at night won't hurt anything (except that it's one more chore to do each day.)

All chicks are being raised by mama hens so I can't separate

I think they're both pullets. Australorps tend to develop comb and wattles very early if they're cockerels. I also would be it based of of their size. I have an Australorp who is 9lbs. She's a big girls and always has been.

Question. Would cockerels have thicker legs at this age?

Sometimes. Sometimes not.
