Hi all, new to the goat world! We are currently looking at bringing home pygmy or dwarf goats and are only open to wethers or does...BUT an opportunity has come up of 2 nigerian dwarf bucks who are 2 years old. Question: if we castrate them now at 2 years old, would: 1) there be any disadvantages or health problems 2) would any typical buck behaviors (e.g., potential aggression, smell, anything else you might think of!) miraculously decrease soon after castration or because they are already a few years old (versus castrating them at 3-6 months) do they persist? As beginners, we want to make sure we know what to expect to make it a good fit for all. Definitely not comfortable with bucks. Thanks for any/all input!
