I would have to agree with
@Georgia460. I have had Bielefelders for about 4 years now. They are a very sweet breed but they are gluttons. I don't mind the food. I also have some heritage RIR and they are also big eaters but I'll take the color over the food too. My Biels for the first two years laid huge eggs in high numbers year 3 they slowed down some and this year production is better but egg size is more of a large versus jumbo.
My heritage RIR are steady layers of large eggs
I also have or have had
Australorp
Brahma
Partridge Rock
Wyandotte
Marans
Legbar
Orpington
Dominique
My Biels are fairly dominant to other breeds they are housed with.
What is the purpose of the new flock; eggs for personal , chicks, eggs for sale? 11 of almost any fairly productive breed will more eggs than you will need. I currently have 1 Brahma , 4 Biels , 4 RIR , 2 Australorp , 1 Dominigue laying. I average 8- 10 eggs per day. Some days 1 get 1 dzn.
