Is my thinking right on this....
You breed (up to) 6 hens and collect the eggs for three weeks. Assuming each hen lays a minumum of 5 eggs/week, that's 30 eggs per week, total of 90 for the three weeks. While those are incubating, you collect eggs for 3 more weeks and repeat from March 1 thru May 15. MAN, that's a lot of chicks!! I've really got my work cut out for me (don't mind the work, just got to figure out how to get all the brooding pens ready)!!

Last year we hatched over 100 live chicks. To be fair, we had two hens go broody, and they contributed another dozen live chicks. We also "control" what the broody hens is allowed to sit on as well. Our goal this year is well north of last year's number. The reason is the hatching of the heritage Barred Rocks we have. If we happen to get some heritage White Rocks, well ..... well...... we might hit 200 chicks this year. I dunno. A new record for us anyhow.
