how long does moulting last?

[chic_a_lay]

It's been a good 6 weeks? No one is laying yet...

Molting can last up to 12 weeks or so. Many will finish sooner, but I have some chickens that seem to almost constantly be in a molt, only losing a few feathers at a time. Even after molting finishes, a bird may take a few weeks to begin laying again.

wondering????????
why don't they all molt together?? this is my 1st real molt and it seems they are all taking turns??
will they all eventually molt or do some breeds not molt as hard?? (barely notice a couple nh reds loosing any feathers)
but 2 having a real hard molt.. they look aweful I also have 2 that hatched babies late the summer and did a broody molt..will they molt again??
thanks
