I don't do meat birds, but have you looked at Freedom Rangers from the hatchery of the same name in Lancaster Co, or Moyers in Quakertown?For anyone who buys Cornish cross meat birds, where do you like to get your chicks? For the past two years we've used Murray McMurray and bought their 'Cornish Roasters' which are supposed to take a little longer to reach processing size (10-12 weeks instead of 8 I think) but have fewer leg problems, etc. I awas pretty disappointed in the meaties we got this Spring. I don't know if they changed their breeding, or if we just got a poor hatch but we had a lot of problems with them. We were hoping to do a second batch of meaties this year but I've been putting it off since I'm reluctant to order the same thing and ending up with lots of leg problems and weak chicks again.
I also have to share a funny... We got some new neighbors last spring and our kids go to school together. The wife loves our chickens and they've started feeding them for us when we go out of town. A few days ago she asked me if I could help her process a few chickens since she had a chance to get 6 free roosters. I said 'sure'. It turns out they are silkies and there were only 3 left. She took them anyway and decided on the drive home that she would clean out the chicken coop in her back yard that they had been using as a shed so that she could keep them. She was eventually planning on getting a bunch of RIRs since she loved our chickens so much but this sped up the process for her and she's wanting to get some laying chicks asap. The funny thing is that they are a biracial family, the husband is black and she is white... and now she's talking about how she's going to have a matching, biracial chicken family too (Silkie roos and RIR hens). She's super excited to see what the eventual 'biracial' chicks would look like between the Silkies and RIRs... anyone know? I expect there is one dominant skin color and she's not going to get the 'mix' like with people but I don't really know much about chicken genetics.
Moyers sells a variety of meat birds, and quite a lot I believe.
As for silkie roos over RIR, i think the chicks will be sexlinked, with the females having dark skin and male yellow skinned. The silkie feathering is a simple autosomal (non-sexlinked) recessive, so none of the babies will be silkied, but they will all carry that gene, so a future cross for the daughters back to their father will produce roughly 50% silkied babies.
