I've had girls do tat to me before, start out nicely laced then the patter goes all haywire after the first real moult... I think that's why a lot of old timers always preferred waiting until after their first real moult to start breeding. because then you know what you've REALLY got to work with...
fortunately, my splash laced girl's lacing is just as clear now as it was when I got her. which is good ince she's my ONLY blrw girl (tho I have 3 lf and 1 bantam roos)
I think the 2 chicks hatched from her so far are a pair... so that's 1 more girl
and delisha's eggs are due next Friday.
There's wisdom in the old timers' methods.
Good luck with your hatch! I have 20 set to hatch Monday but they will be heading to a new home.
