i'm pretty new to goats but i'll tell you what i have experienced so far...i purchased a 2 week old pygmy doe..didnt de-horn her when she was that young..(mistake)..anyways..she has never been agressive at all to anyone...when she is out of her pen in the yard with us...she just follows us around(we spent alot of time with her)...she is VERY friendly and knows her name..they say they are equal to or more intelligent than a dog......than it was time to put her outside in her barn(she was inside,it was to cold for a baby to be outside alone, in january, in new england.) and she cried and cried..she hated being alone...so i recently purchased a male(soon to be fixed), alpine..and he was a week old...and the vet i got him from had already did his de-horning, so when i put the two together..it was a diaster...Cricket(female)..kept ramming him...being very rough..trying to establish her position with him...so...unfortunalty..i just ,2 days ago..had to bring Cricket in to be de-horned and it is a horriable thing to do at her age...very painful(i've been sick to my stomach over it)..but they did put her under anestiea...i should have gotten her de-horned as a baby....that is my big lesson...if you have more than 2 goats...they both have to be de-horned...or both have to have thier horns intact..or there can be serious injurys....but i love my goats..will always have one now...my male baby is just as affectionate as my female..i just love them!..good luck with them!..Wendy
