Hello I am doing a staggered hatch. First set eggs on 4/12. I have RIR roosters over RIR, BPR, and Cinnamon Queen. I hope the breeds are true so I can breed my own Black sex link chicks. Only 10 eggs were for sure when I candled them. I ended up pulling 12 eggs and replacing with 25 eggs on 4/22. So hatching on May 3 and May 11. My turner won't work with so many eggs so I am using the 2 x 4 method of tipping the incubator for turning 2-3 times a day. My two RIR roos are huge, tallest chickens I ever had. I hope to raise the roosters as free range meat birds. With a successful hatch I will have pullets to sell. I will keep these birds for a few months until I know that the sex link bred true. Then I can confidently sell day old black sex link chicks as pullets. I raise standard roosters as meat birds. I butcher them young while they are still tender.
