I've got this black pullet (not sure if BA, BJG, or mix) that's 20 weeks old & she just started laying the other day. I posted about it. I found 2 very small eggs in the same day & one of them was in the nest box along with a bigger egg. I'm not positive she layed both small eggs or not or the big regular egg for that matter. I have 2 other POL pullets but haven't seen them in the nest box at all. Well, over the past few days, I've gotten a total of 4 of the really small eggs...assuming all from the black pullet. I've had POL pullets before & know that many times their eggs are smaller, but these are really small. I've never had any this small. Will they ever get bigger? Is this a typical egg size for a pullet just starting to lay or are these considered "fart" eggs? The other two like this I cracked did have yolks & appeared to be fertilized. Here's a couple pics that has 2 of these eggs next to a regular egg. I put a quarter in one of the pics to show size comparison.
