i had an EGGS buck for a year, he was 375 at 4years old, it verys by bloodline, and on managment, also alot of red head white body animals out there are not pure so there are alot of small scrubby goats out there being sold as Boer, so it all depends on whats in the mix really,
I don't have any full grown wethers. We see alot of them at our county fair and they weigh between 80 - 140, but these are Boer goats going to market and that are less than 1 year.
I've got 2 does that just gave birth - 150 lb, and 110 lb.
Its some info, but I haven't answered your question.
