Are early tail feathers an indicator of "pulletry" (I know, it isn't a word, but sure sounds like it could be don't you think)? I read somewhere that pullets get tail feathers before cockerels. I have three BRs that are like three weeks old and only one has tail feathers. Of my 6 one week old BO chicks, five have tails growing and one is, well, bringing up the rear with no tail feathers yet. Does that mean I have a BR pullet and 5 BO pullets?
