Hi Stephb , ours are about 12 month old, they were given to us because they have angel wings, saves having to clip them.
They started getting territorial about three weeks ago so we knew they were coming up to laying , so we should be picking up 1egg per bird every other day
Yours wont be far behind , just make sure they have some straw to make a big nest with. ours decided the stallion's stable was a suitable place, he's not impressed.
