@saul ok that's fine .thought I'd offer as I mainly wanted whites and reds . She is only here as she has grown on me .intelligent bird and good flyer..
Do you see a difference in the performance between your whites and blues ?
@mizmo Yes that would be great Mizmo, let me know if you get a YB surplus to requirements. The whites (sold to me as Logans with no pedigree) seem to mature in their flying slower and do some "wing over" unstable looking turns as YB, I men in the first 3-4 weeks of flying out, but I don't see a difference as they get a bit older. They seem a slightly larger bird, they are less keen to be handled, and more defensive of the nest. I've got one extra white YB this year and 3 whites on the nest with a further 3 eggs so maybe you would like some whites from me? I can't say anything about their performance beyond they home in from 20 miles. I m near Guildford but Im sure we could find a way.
