Llamas stop to pee and poop, they do not just keep walking like horses do. Some of them prefer to do this next to the trail instead of on it, and it takes them a few minutes. When one does this, get the others to smell it and they will all go, eliminating another stop.
Llamas will follow you, but they prefer to be able to see all of their companions on the trail. If they get too far apart they will get anxious and misbehave.
Some llamas prefer to be first in line on a narrow trail, some prefer to be last, and they can change their minds about that after an hour or two. Work with their preference and you will have a calm, cooperative companion.
Llamas are a modified ruminant, having three compartments to their stomach. They are designed to eat slowly, all day. You do not need to allow them to stop and eat trees and bushes along the trail, but when you encounter a delicious meadow, then stop for lunch or snack yourselves, allow them time to fill up.
Plan on stopping long enough for them to eat the next day. Forest rules prohibit staking animals within 100 feet of streams or lake edges. You can, however, let them graze there for a short time if that is the only grass available. Azalea, and Death Camas lily, deadly poisonous, often grows close to water or wet meadows. Some green plants, even some grasses, may Not be llama feed. They cannot live and work on pelleted feed alone. They require a few hours of Grass to fill their 3 stomach compartments so they can continue to work for you. If you fail to provide adequate sustenance they may lie down and refuse to move any farther.
Llamas need a dry place to sleep. If there is a wet meadow, let them eat then move them to dry ground for the night.
Llamas can get their tie out line tangled around short trees or bushes and strangle during the night. Be sure each one has enough clear space for safety.
Never leave llamas tied out alone where you cannot hear them, for more than two hours. If there are places you want to explore while camped, take them with you without their gear, or leave someone with them.
If a llama gets loose, do not chase them. Put a cup of their feed in a pan, shake it so they can hear it, calmly and slowly approach or let them come to you. If they have no halter or no lead, have one ready to slowly put over their neck when you are close enough. Slow and calm, control of your own emotions is the key to capture. Tie the lead around their neck to a tree, then find the halter.
