How many standard eggs can a bantam incubate?

[Robin'sBrood]

Just went out to check on my little Daisy girl and I found her sitting on the outside of her nest box looking in. Why? Because her sister, Milly, is now broody and had taken over Daisy's nest.

So, I marked and gave Milly her own 6 eggs in another nest box. Didn't surprise me at all, they are my only two girls who have ever gone broody, and they tend to do it back to back.
