Hi
I have been a llama lover for many years, and have worked with and shown them for many years. I think your llama should be able to go out with the minis. I have heard of some intact males used to guard sheep and goats crush ewes and does that were in heat when they tried to breed them, but I have never heard of any issues with horses.
It is probably too late to shear now, but around the end of April/early May next spring have her sheared, nails trimmed, teeth checked by the vet, etc. You can find a shearer and someone to do nails by you on Google most likely. Having a set of stocks helps greatly when vaccinating and trimming your animals nails. Around here on the East Coast we have to worm monthly year round against a type of parasite carried by slugs and snails called Meningeal (sp?) Worm. They can stay dormant for up to 3 months in the animals system so you still have to vaccinate in the winter months. We do an IM injection for our herd, I'm not sure if you can use an oral paste for it, I would research it and ask your vet.
I would however separate the llama from your horses at feeding time. A llama herd is much more docile than a horse herd. Most llama quarrels are usually solved with a switch of the tail, a lift of a head, or the ears being laid back, and rarely, spitting. You do not see llamas kicking the crap out of eachother over food like horses do from time to time (boy am I glad mine are over that
), so seeing as the fact llamas have soft padded feet, no upper teeth so they cannot bite, and their only real natural defense, I could easily see a llama being pushed out of the hay pile by bossy horses.
Other wise, I can't think of much else but enjoy your new llama!! They truly are great animals. They are so wise and gentle, great with kids, and just over all great pets. So many think that they are horrendous animals that will just attack you and spit on you, but when you walk through a barn full of them, you become so calm and they are just great animals (how many times have I mentioned that? lol).
My linkHere is a great link for a web store filled with llama tack and supplies that we have done business with for years, they are great!!
My link And this is a GREAT book for any llama or alpaca owner, old or new, definatly a reccomended read, I have it in my llama library!!
Well, that is all I can think of for now. Oh, and I can't wait to see pictures of your new friend
