Small eggs suddenly?

[CritterHill]

My chickens are nearing a year old and have been laying for months now. I've been getting decent sized eggs all along, but this week, I've been getting a lot of small eggs!

Any idea what could cause it? Could it be because I don't have their heat lamp on every night since it has been getting warmer?

They are all Polish hens, just under a year old. Thanks.

Eggs size changes for no reason that I have found. I have hens that will lay all different sizes all week long.

 

[what was i thinking]

i have one that just started to lay after her molt. the eggs are much smaller then she was laying before her molt?? i just figured they do that sometimes.
