My BO has always laid small eggs. Not quite that small, mind you!
I have read countless reports that Orpingtons are meant to lay large brown eggs, but what do I get from mine? Small, creamy white ones!
One girl, now 11 months, is just starting to put up 60 - 62 gram eggs, which is great. But before that her eggs never exceeded 51 grams, and sometimes were as small as 48 grams.
The other BO has stopped laying recently, but always laid 50 - 52 gram eggs as well. She had started to improve her egg size too, when I started adding a supplement to their diet, but then she went broody and well.... no more eggs.
My RIR's in contrast, put up large to extra large eggs right from the get-go. Their average is 70 - 72 grams, but we have had some at 80 grams and one whopper at 118 grams!
