Had the same experience with my current clutch
I had ordered 5 brahma eggs from a local breeder 2 came in cracked, 3 had already got the spider veins before being shipped but died before my girl went broody the extra 1 has no show, definitely not ordering from him again
Last year January was mum(lulu's) turn
That was where her daughter currently on the eggs was born, a day before valentine's
So this year is daughter(survival's) turn
