Sounds like they’re still practicing. Their flights will get longer and longer. At some point they might be spending a day or more away and then returning.
Sometimes wild geese will migrate shorter distances, like to a local wetland or lake, then return to their home range if the weather worsens...
As long as they choose. If they have an available food source and a nice climate year round they may stay.
Keep in mind that unless you purchased them from a licensed breeder canada geese are protected under the migratory bird treaty and so are illegal to keep.
