When you do the breeding can you stagger so only some hens are being used at any given time? It would setup for what are called cohorts where you have groups of biddies all about the same age within a given cohort. Biddies within a given cohort all require the same type of resources making so management easier. I also have to do the multiple cohort thing because simply not enough space. By the time second cohort is ready to start the first is ready for the first round of weeding out culls. I try to start collecting eggs for second cohort when first is about 6 weeks post hatch. That also allows for retrying hens used in that were a bust in the first round.
thanks centrarchid this sounds like the way to go to ensure all the hens get bread Pluto this will make it easier on me with the markings and record keeping.... ...
