When will my girls start laying?

[suburban]

I have 2 Australorps aged about16 weeks old.

One is quite a bit bigger than the other and has a very red wattle/comb (not sure of the correct name for that) she seems to be the boss.

I've noticed they both sleep together in one nesting box snuggled up together, not on the roost in the coop.

At what age do they usually start laying?

I have 5 BBL Polish girls hatched out in March. Not one egg from any of them... yet.

Good luck.

They normally start at around 26 weeks, but I have seen them start earlier.
