I'll first give you a little backstory to help you understand. I live in pennsylvania so it does get cold at times. I just started raising chickens for extra profit. I would like to start broilers and order 30 chickens every month to replace the old ones as I go to keep a constant income going seeing how most chickens are ready for processing after 3-4 months but also would like to keep a flock to myself for egg laying so I would have my layers and then broilers. At the moment I have 6 khaki cambells (Ducks) 5 Red Productions (Pullets) 5 Black Sex linked (Pullets) 5 Plymouth Rocks (straight run) 5 Red Rangers (Straight run) 5 Rhode Island reds (Straight run) I'm trying to decide which ones to keep and what should be processed. They are 2 weeks old to this day. I would like to keep layers from this group and then order buff orpingtons as broilers from now on every month. I'd also be willing to order some new layers if needed. I have lots of space and just need some more insight. In other words if you had this flock what would you do with them and how do you think I should run my plan on broilers and layers?
