I have four goats.
Valley is a NubianX Lamancha and she is tall like a nubian but looks lamancha. she is the BEST goat i've ever seen. she runs with my horses and gets along with pretty much everyone shes always faster then my horses to get to me she leads in hand anywhere and even jumps in hand. I've never had a bad habbit from her at all and she has a wonderful udder.
Then I have kid. Her mother was a PURE lamancha (Very shy momma) she died after the birth of kid (and kids twin sister) and kids sire was supposed to be boer goat but I never seen him. But I saved kid and bottle fed her. Kid right from the beginning was stubborn but friendly LOVES to eat paper I had to force feed her and never enjoyed bottle feeding truely untill the next kids I bottle fed.
Kid is fat like a boer goat but she was a naturally polled goat and she is a good natured but athletic goat. She does not like being away from the house she starts to go a bit crazy. I don't recommend boer crossing lamanchas much. however kid is a good goat.
Then I have two alpines (also owned before) and I can tell you 100% from me on alpines they have a wonderful udder and awesome loving personalitys I chose my only buck to be a alpine goat. they are gentle and easy going goats.
