Hi! That's interesting and something I always meant to ask of 'chicken-breeders'.
I am a daylily hybridizer and the practice is to list the [pod parent (female) X pollen parent (male)] and thus and such from there.
I never thought that it might be different for birds, so I do it just the same (female x male), for the birds.
All my records are written just backwards then, haha. Doesn't surprise... I do many things I do bass ackwards here. If I can understand my breeding records, it's good.
