2 Boer are does and I believe the 2 Nigerian Dwarf are whethers. Don't know age as I have not had them long. Hoped to use them to chew down shrubs/trees and weedy species in pastures and did not work out as planned as they found their way back to the farmstead each time. They are pretty attached to each other as the previous owner had them together for years. They are friendly and will eat out of your hand, but won't let you get close enough to touch or pet. They are fine around kids as my 3 year old can feed them by hand and walk around with them. $75 each for the Nigerian Dwarfs and $100 each for the Boers. Buyer picks up and hauls.
