I think that this is an excellent post and I really hope that it takes off. I've researched bantam egg information and there really isn't a whole lot of good stuff available with regards to size and production. Having raised bantams in the past I do know that 1.The eggs taste exactly like regular full sized chicken eggs. And 2.Some breeds do lay better than others. They are bigger than quail eggs but definitely smaller than a full sized chicken egg. I typically eat 2 full sized chicken eggs per day, but when I'm eating bantam eggs I have three.
My personal breed information: Easter Egger bantams (EEB) were pretty good layers, usually 3-4 eggs a week, as well as my Mille fleur d'uccles, also 3-4 eggs a week. Typical bantam sized eggs. But both breeds did slow down a good bit during the winter months.
I'm currently raising 3 different bantam breeds.
1. Buff Brahma's
2. Rhode Island Reds
3. Barred Rocks
My hope is that by this time next year I will be able to have and share some good reliable egg stats for those breeds.
I hope others with different breeds share their bantam egg stats as well. My goal is to find a good egg laying bantam that isn't broody crazy. I understand that broodiness is a characteristic in bantams, but not all bantams broody the same. lol
