IF there is a lethal gene. No one knows at this point. Right now its an issue of poor hatchability for what appears to be SG only. Hard to know how many are affected by it since many old timers are not on the net. My understanding is that when you outcross to another breed its preferable to go to one of the foundation birds if possible or a closely related breed. Neither of those is possible. Dorkings are ancient with apparently no Asiatic influence. I do think other breeds have been added in here and there. I think Leghorns have been used in the past which is why so many birds have white in the ear lobes....which depending on who you read is considered a sign of purity or not. The SOP allows for 1/3 white in the lobe. They've been instrumental in the creation of breeds such as the sussex, but it would make more sense to use a different variety than go outside the breed.I would think that if I was facing a dead end with the birds I had chosen to raise, that outcrossing to another breed would be perfectly acceptable. Yes it will cause some problems and yes it will take years to get to where you really wanted to be in the first place but with lethal genes cropping up and all the birds here being so very closely related, wouldn't it be an acceptable option?
Also, YHF has apparently done away with the lethal gene in his flock. I don't remember ever hearing him talk about low hatchability and/or survivability among his chicks... and he has some really nice birds.
YHF crossed varieties. Which is where I think I would go if this was my variety and I was having problems. Mr. Dorking (thanks Karen, the name may stick!) implied last I talked to him that crossing varieties was no big deal if it would get you where you wanted to go. He likes to create colors so I'm sure he's done this and other things too. I'm not on Facebook (seriously I don't have that kind of time) so I don't know how extensive the problem is with SGs. I just tried to hatch some shipped eggs for Reds and while I can say the hatch was incredibly poor, I don't think it had anything to do with the birds. Rather I'm just experiencing really poor hatches this year when hatching shipped eggs for others. Inspite of the crappy winter the north east has had, my order from Horstman's is on track. So I don't think he's experiencing any problem with Reds. Reds do seem to be doing ok vigor wise.
I just really have no experience in solving this kind of problem. Just seems to me using another variety is less work than going outside the breed. I'd be interested in how others have solved such problems with their breed.
