Just started laying but which two?

I have 3 hens, I'm in the UK and i have one speckled (like a barred rock) one blue ranger (grey body black head very large) and one that looks like a white sussex ( i think she is a white sussex) anyways, they are about 24/25 wks old now. They just started laying last week. I only ever get two eggs a day sometimes only one, but I'm wondering which is laying and which hasn't started yet. I have a suspicion it's my sussex who hasn't started yet. What do you think by the egg colour? Also is it possible to eat the eggs now? or do they need to lay for awhile before they're edible? sorry for all the questions, these are my 1st chickens so I'm new to all this. Here's my girls and the first 2 eggs and the 2 i got today.

I am not sure what color eggs different chicken breeds lay but I do know that if the comb is bright red they are probably laying. The eggs are edible and you don't need to wait

Certain breeds will lay specific colored eggs. I'm not sure on your breeds, but for instance, BRs lay a medium brown egg where a Maran lays a dark brown egg, and Ancona lay white.

There's a possibility that all three are laying but they're staggering their "day off".

Best bet is to check the nesting boxes after one comes out and see which egg is in there, then remove it and wait for the next hen to go in. Might take a couple days, but with only 3, not too time consuming. We have 22 right now, and we can tell which egg came from which breed, and sometimes a specific bird based on certain characteristics of the egg. Chipmunk, one of our EEs lays a freckled egg, and so does one of my Cochins. Just takes time to investigate and figure it out. They'll pretty much always be the same color egg from the same hen.

The eggs are fine to eat from the very first one they lay. First eggs are smaller, but they get bigger the more they lay, should be full size within a couple weeks. Eat em up, they're perfectly fine unless you've given them any medication or wormer.

Hi! Welcome to BYC. I'm going to go out on a limb and say that if you got two light brown eggs on the same day, that's two different hens. And the darker brown egg is therefore from a third hen. So all of yours are laying.

Good point.

Save them up for a few days and see if there aren't 3 different eggs, too. Most hens don't lay every single day; they'll take a day off every week or so.

Agrees all 3 are laying if size, shape, color of eggs shown are consistent.

Could examine vents and pelvic points to confirm.
Vent Appearance:
Dry, tight, and smaller - usually not laying.
Moist, wide, and larger - usually laying.

Pelvic Points 2 bony points(pelvic bones) on either side of vent:
Less than 2 fingertip widths apart usually means not laying.
More than 2 fingertip widths apart usually means laying.

Oh, and, Congrats and Welcome to BYC!
