I hear ya and I'm not going to outcross our dorkings at all. Just thought it was interesting that they wrote 3 articles about grading in the same bulletin. Have to admit it was an interesting read. I have already been applying the same basic breeding method with our ISA Brown back cross project. Thats what I was calling it before I learned it's called grading when applied to chickens. I started with a nice looking (but mean) rhode island red rooster. and my best laying ISA Brown hens. I don't like RIR's but don't feel the same about ISA Browns. Anyway since ISA's are basically 50% RIR I thought he'd make a good bird to start the project with.I've been raising Dorkings since 2005, but didn't get the SOP until last year. I was so upset when I read it and realized how many defects I had been breeding.Not having the SOP when I started breeding was my worst mistake.![]()
Make sure to read the first sections, not just the breed description. So much valuable info there. Even the glossary will help with using the correct terminology on that other site.![]()
Regarding grading, I am a purist and will not cross breed a foundation breed. That opinion got me condemned on another thread, so beware of making that opinion public.
You can get bigger birds by selecting for it in your breeding program. It's slow, but entirely possible with patience. I saw an old article with illustrations for each year and the progress made over a ten year period. There were only subtle changes from year to year but a transformation when you looked at the decade.
Finding a mentor that is a Master Breeder and APA judge has been a great help in applying what I read in the SOP.
I also waited way too long to use a scale. I'm still not sure if I'm getting an accurate weight. I bought a food scale but the surface is slippery. I ended up using an infant scale for mature birds. Lots of people say that they use postal scales but the ones I've seen for sale are expensive and too small.
Now I have the dilemma of my birds with the best weight have white ear lobes. My birds with some traits that I need have lower weight. I'm trying different combinations to see how I can resolve this.
I did cull some nice type/sized birds, early on, due to improper color. Another mistake. Type/size is the most important. Disregard color until you have type. At least you have single color varieties!
What I'm shooting for is a white bird with brown or red markings kind of like an ISA Brown rooster. But I want all the birds to be the same color, hens and roosters.....
So it basically takes a rolling breeding or 2 to get there since they are sex link birds. IB roosters are white with brown markings and the hens are white with brown markings originally. When we crossed the RIR to the IB original hens we got a brownish rooster. Then when we back crossed (75% IB 25% RIR) we got a nice white rooster. He's got a nice attitude like an IB rooster too.
From here we are going to use him on some fresh IB hens we just purchased back in February. Figure we should get some white hens from this second back cross which is called hexing (87.5% IB and 12.5% RIR) when breeding plants....
I like doing different stuff just for fun but this is probably as close as we will ever get to grading. Sorry if i got off topic there but just wanted to state why I'm interested in grading.... Have no intentions of ever outcrossing dorkings to do a grading project with them...
