Hello and welcome to BYC!
Glad you joined.
Good luck with your breeding plans. It does sound like you need more pens.

I think its worth to note that most of your birds are mixed breeds to begin with, and while there is nothing wrong with that, when you breed hybrids they lose some of their hybrid vigor in the next generation. So since your main goal is selling eggs and using extra cockerels for meat you may want to consider breeding mainly your pure bred birds to create the next generation since they will most likely grow quicker and have a better lay rate than hybrid crosses. This is just what I've read so you should still do your own research on the matter if it is important to you. Or even better, experiment with your own and track it! Since you have some BR hens you can make your own black sex linked chickens which will let you know right away how many layers vs meat birds you have.
Sorry, this is confusing to me. My brain kind of hurts from work today haha. If you could list it out like example below I would find it easier to follow. But the point I'm trying to make is if you breed first generation hybrids then you will get the meat and egg vigor both in the offspring and don't need all the separate pens. Maybe separate by generation or just mark them. A hybrid bcm x BR or bcm x SLW should give you good layers and a decent amount of meat on the cockerels and they should grow out quickly so its a dual purpose bird. BCM X EE would make a nice olive egger. So if you want straight up blue eggs then you just need to separate the EE. Otherwise, keep everyone covered by BCM. If you can't tell your current sexlinked eggs from your pure bred eggs for egg collection purposes then just keep them separated until you are done collecting. Does that make sense?My thought was pen one would be barred rocks pen two would be some new stock of bcm roo bcm hens and get some breeder quality americaunas chicks straight run in the hopes of getting a great roo and some good girls for the bcm with my Wyandotte’s I believe the bcm over Wyandotte’s is a red sexlink take that americauna roo into pen 3 over all my Easter Egger and just general mixed layers leaving the fourth pen for meat birds does this sound like what you are saying
