I don't about anyone else, but I'm working towards a black flock in part to benefit color projects and mostly because blacks are so gosh darn pretty. Haven't really heard of any other black leaning flocks out there, most seem pretty splash heavy still. Going to have one BB SiAm pen this year with the rest being split pens (using unrelated birds -- these offspring splits will be crossed back with the all SiAm offspring to reduce the impact of their relatively close relation). Split pens will be mostly BB, with one pen BBS.
That makes my sharing goal this year: egg sets that are 1/2 all SiAm and 1/2 all splits - where the splits are coming from the unrelated good line blacks I crossed in. With any luck, the folks receiving them will heed my suggestion to only cross the silkied to the splits or unrelated (so they are crossing the least related lines in my flock if they have nothing else to breed) for their first home-hatched offspring that are SiAm and splits. That'll also give them time to bring in their own unrelated birds to start their projects with too without getting desperate and crossing SiAm to sibling (or half sibling) SiAm.
If this year's breeding goes to plan, that'll mean I'll have a choice of black SiAm to cross with a boat load of black split Am (new blood from 2 unrelated roos, 4 unreleated hens; 3 pens with SiAms; all good blood line). This would be setting up next year's ultimate goal of the black SiAm black split Am only breeding flock.
Has anyone tried shipping chicks yet? I haven't, not sure what it'd take to do it but I know we see a lot of requests. On one hand, I just don't like the idea of putting chicks through all that, especially since they aren't quite as hardy as standard chicks. On the other hand, I know I'm getting to the point where I will need to cull out blue/splash and this would give them a much better chance of being breeder birds in another flock versus just a layer or culled roo in mine.
