Need info about bantams!

[Boggy Bottom Bantams]

Lord no, They all lay daily or every other day at the least, when in season, most will not produce year round. March -October will be your heaviest months, I have 17 colors of the d'anvers you mentioned, and when in full swing, they lay 1 a day, same with my silkies, and o.e.'s.
The only problem with 2 of them, the silkies and cochins, they tend to go broody a lot, so most will lay less than the other breeds you mentioned

 

[call ducks]

i find my bantams to lay in the spring up to the fall , mine don't lay in the winter because it is just to cold too lay here for bantams
