I have three bantam hens that are production line broodies.
Step 1 All three set three nests all the same day
Step 2 After the chicks hatch all three lay in a common nest and 1 sets this nest while 2 tend to babies
Step 3 When these chicks hatch 1 hen takes the oldest chicks, 1 hen takes the youngest chicks and they start another common nest.
Step 4 Start back at step 1
These hens will do this all summer long, raise a lot of babies and since they share duties on the nest they all stay in top condition.
