I have a 6 week old bourbon. Does the peeping it's making determine if it's a boy or girl? it peeps then makes a louder adult like peep? Sorry newbie here. Can you tell by the feathers like a chicken? Sorry just really want a hen.
Doubtful if vocalizations will clue you at 6wk. If you hatched it, or got it as a day old and observed it spending seriuous time strutting its tiny self around, that can sometimes be a give away (our three toms were strutting at 1.5wks).
Below is a seven wk old RP/S cross. Female. Note the plumage up back of neck and on head, observe the rather long, rather ovoidally shaped skull (male poult's heads tend towards a slightly more short/cubic shape). Male's legs also tend to be slightly longer/slightly greater diameter along the short axis.
Our jakes started garbled gobbling at about 3months (heard them for the first time one night when they saw a opossum).
Some commercial producers have bred BB's for longer feather length in males so as to make determination simpler (don't know how that's worked out for them).
