"Kindergartners" and "Teenagers"

I have taken to calling the calves across the road "teenagers" (the ones that were weighed a few days ago http://trekincartwrights.blogspot.com/2017/06/time-for-weigh-in.html), and the recently weaned  ones I call "kindergartners". The kindergartners are quite a bit doofus...

Do you see that the majority of the cows are around a feed trough there in the back left... but these 5 are here staring at the truck, like they think there must be something else coming?

The teenagers start heading for the trough area as soon as the pickup appears.

Dwayne starts putting the buckets of food into the troughs.

Here they come!

Kicking up dust as they trot on in...

Some might be slightly slower, but they all know to come to the trough to eat!

No one looking around or coming to the pickup truck for something else!

The "kindergartners" were weaned a month or so ago; the "teenagers" are a year older. There does not appear to be a leader developed out of the kindergartners yet, they seem to just mosey around in a group. A number of times I have seen them eating across the field in a line shoulder-to-shoulder. It reminds me of the intro to a show from the 60s, "The Monkees" - I found a video of the intro - the "walk" is about 4 seconds into it: https://www.youtube.com/watch?v=vHHZb7c3Qy8&list=RDvHHZb7c3Qy8
