Once they start, there's no stopping them

we have had our 3 for 18ish months and one hasn't had a break. One lays every other day now, and one has come out of a months moult and laying every day again.
They took between 4 weeks and 12 weeks to start laying when we got them as POL.
It worries me that the constant layer will burn herself out at some point as it must take a lot out of her.
They are hybrids so will dwindle off quicker than breeds tho. Will wait and see. Just want more different breeds now
The original layout cost I dare not work out. Their welfare was top priority so a large enclosure was built. If/when we move it will be dismantled to travel with us
