The last few dual purpose birds we have eaten have been tough. How can I make the next birds more tender. My birds tractor range 5-8 hours a day, at least 5 days a week. Then I feed them meat crumbles. Should I change the feed to something better? I don't feed a lot of greens or treats, should I add some to their diet? I also noticed, most people dress their birds sooner than I do. I usually have to wait until they are 24 weeks or more. Otherwise they are too bony. The breeds are RIR, Barred Rock, and will be adding some giants soon. Should I be looking for a different eating breed? I really don't want to do Cornish. I usually keep a few hens and eat the roos. I will be incubating my own eggs next year and am looking for a tender, juicy bird.
