Egg sizes over time

[aart]

Guess I'm going to plunk down down a few $$ on a micrometer at Harbor Freight.

You can get a decent digital caliper for about $20-30.
Or you could just weigh them

Pullet A? Come on. They need nifty names to go with their eggs!

Any excuse for a trip to Harbor Freight.

My wife has nicknames for them, to me they're a resource that are fun to watch.

So I bought the micrometer and had been holding all the eggs until today and got a surprise, the ISA Browns are laying

So let me give the sizes of all the eggs we've gotten so far.

This is a great idea! I may have to do this when my pullets start laying.

Following this thread with interest! We first got chickens 2.5 years ago (AmberLinks, ISA Browns, Golden Comets, Rhode Island Reds, Barred Rocks and Black Australorps). All laid big eggs. This spring, we ordered chicks since our older girls had slowed laying, but we ordered Cream Legbars, Sicilian Buttercups, True Green Whitings, Buff Orpingtons, and Silver Laced Wyandottes. Every one of the new pullets lays a very small egg even though they were advertised as laying large eggs. The first egg was only about 31 grams, as compared to the 77 gram whoppers we get from our older hens. I have noticed the eggs getting a little bigger, but I'm still curious as to how long that will take...

@melissamc that was my interest. I've seen where people weigh the eggs and that's interesting too, but size development was my curiosity as I hadn't seen it done on the forums before.

I have weighed all my eggs. The very first was 17 grams, the second was 25. Knowing my pullets as I do now, I think they were two different birds. I have three Black Australorps, and they started laying at 19 and 20 weeks, back in the first week in August.

Most of the eggs are 47-50 grams now, with an occasional 51. I have had three double yolks, all from the same pullet, at 64, 65, and 68 grams. They are slowing down a bit now, with the shorter days; I get 1 or 2 eggs a day, instead of 2 or 3.

A digital kitchen scale was $20. I got it for measuring dry ingredients for baking. It works great for that too.

This is a thread where someone weighed the eggs over time. It might be interesting to some of the people reading this thread.
