How long until these girls start laying?

[Hazel feather]

This is forest , she is an olive egger ( cream legbar x cuckoo marans ) she is almost thirty weeks old and no sight of any eggs yet . Her sister started laying at sixteen weeks but died of prolapse shortly after she began laying . Forest eats a mixture of growers and layers mash .
Thanks for any help!
As you can tell I’m very impatient!

Both still look to be in their 'teen' phase. It will be a while before they start laying.

Of the 3 pictured, Kaye looks the most mature and may be the first one to lay but I think you have a bit to go for all 3.

Combs will be bright red when they get closer to Point of Lay.

Some other signs that you're close will be squatting, more interest in the nest boxes, and they seem to get rather loud. Making a lot more noises.

Thank you everyone , looks like I’ll just have to be patient!!
