2 chickens still not laying.

[NerdTime1997]

First let me tell you that we have 5 chickens, 2 Rhode Island Red, 1 Buff Orpington and 2 chickens that look to be red sex links. About a month ago we got our first egg and within a week we started getting 3 eggs on a daily basis.
I was wondering if one of these breed starts to lay later or how to tell which of my chickens aren't laying?

3 eggs out of 5 pullets every day would make me think all 5 are laying. Most pullets do not lay everyday that first month plus it's winter. Each hen will lay an egg that is slightly different in size, shape and color.

It never crossed my mind that all five might be laying, you're probably right. Thanks for the perspective.

Comb size and color can help determine who's laying and who's not.....Sometimes...I've found it to not always be accurate.
Plump, shiny red - usually means laying.
Shriveled, dryish looking and pale - usually means not laying.

You can also check their pelvic bone spacing, which I've found to be more accurate.
2 bony points on either side of vent:
Less than 2 fingertip widths apart usually means not laying.
More than 2 fingertip widths apart usually means laying.
