Brown-egg chickens now one is almost white w/course shell?

[Pump Hill Peeps]

Is there a deficiency or blockage that now few eggs are almost white with almost calcified shell. noticed a few whitish poops in house too??? Any suggestions?

You didn't state the breed or strain or the hen.

Regardless, it is likely normal for that hen. I've a black sex link or black rock as they call them in the UK. Her litter mates lay a darker brown egg. She typically lays an egg that is quite pale and oft times rough shelled. It's just the way she processes in her reproduction. BTW, she is very, very fine hen otherwise.

As a hen gets further along in her laying cycle prior to molt, the eggs tend to become lighter in color-perfectly normal.

The chickens are golden comets. we have 9. when do the molt? is it in the spring like ducks would?
