Oh yeah, the SOP book that I thought about getting but is waaay overbudget.
I thought that in america, you didn't want the pointy tail? but someone on here said that the pointy tail is good?
The ideal in the US is generally about 7 feathers viewed from the side on a hen or pullet. (But, if the frame of the bird carried more or less in a balanced fashion, that's fine.) So, yeah... not the pointy tail. Beyond that, you want the bird to be nice and wide so that viewed from behind they have a nice "tent". Basically no part of the tail on a hen or pullet should really remind you of "pointy".
I posted a photo of an Isabella hen a little ways back that has that seven-feather spread.
This is a common distinction between hatchery and standardbred birds that I've noted. My hatchery birds generally only have maybe 3 or 4 feathers visible when viewed from the side.
I believe the Italianer-type (the European Leghorn) overseas has a fairly different standard than ours. I haven't read their standard, specifically, but I base this on what I see coming across the pond as class winning birds and also in conversations we've had in Legbars about how the type should be Leghorn, but EUROPEAN LEGHORN over American Leghorn.
