Keep colostrum on hand. Some new moms won't have milk or it will be slow to come in. Some new crias are weak. Don't wait until you have a problem. There is nothing sadder than an owner calling to distant llama neighbors at midnight in search of life-saving colostrum.
Llamas are curious.
They explore everything. Don't leave potentially dangerous lumber, wire, wheelbarrows, baling string, tractor parts, or brooms and shovels where they can reach them, get tangled in them, or chew on them. Take a tip from the Boy Scouts. Have a plan for every contingency. Talk to your vet or an experienced friend who can tell you what to have in a first aid kit.
