I'm doing my own meat bird project this year. I haven't figured out which breeds I'm going to use, since they suggest 3-4. I have White Rocks and Dark Cornish to start and they are about 1 month old. Now I need to decide the other 2 breeds. I've heard several different suggestions on how to breed what with what and I'm still a little confused. I heard before this post that you should start with 4 breeds. Breed A with Breed B and get C (not sure if I'm "terming" this the correct way...I'm genetically stupid..lol) Then you breed D with Breed E and get F.....THEN you would take Breed C and breed it with Breed F to get the finished result??? Confusing. Then I read differently on here, and I heard to take 3 Breeds.....Breed A with Breed B and get F1, then take F1 and breed it back to Breed A or B. So anyways, I'm still debating which other breeds I should use. I also don't care if I get a gigantic table bird. I'm just looking for a meaty bird that will feed my family for a meal and then maybe a bit left over. I also don't mind waiting a few weeks longer to get that result. I've found that different sites have different information on how fast breeds mature, etc. One may say that a certain breed matures fast while another site says thats its a 'medium' growing breed. I still have alot of reading to do and fast because I want to get these other breeds soon. At first I was only going to try and breed the Dark Cornish roo over my White Rock hens...so for the first time ever, I ordered from a hatchery. They shorted my order by half and sent their apologies. I wanted to see what I'd get by using hatchery stock and didn't want to invest a whole lot if I didn't somewhat like the end result. Now I wish I would've just got them from a good breeder. My White Rocks don't look all the same and neither does my Cornish. So I'll be buying all good stock from reputable breeders soon here.
