He will probably finalize his growth pattern this year or early next. Cattle can take anywhere from 3-4 years to reach mature size. Nicholas is one of the few male Jersey calves who will a long life. Most are killed when they are less than 24-weeks of age or never make it past the age of 2. Of course, it would not be a true sanctuary if we slaughtered the animals here!
Jerseys are a small breed of cattle. The photo below does not offer that perspective. This will give you a better idea of the Jersey size. Elsa is a 15-yr-old Jersey cow on the left. Nicholas is on the right. The fencing is 5'.
I wish I had a picture of me with Maddie, a Holstein (black and white) cow. I am 5'10". I cannot see over her shoulders or back. She is the tallest Holstein I have ever met. When Nicholas stands next to Maddie, he looks like a calf. The 2,000 lb Charolais steer at the sanctuary manages to look smaller than her.
Nicholas barely looks like his younger self (the second photo). He still has that white marking on his right rear flank. It looks like this now. I should post photos of Summer and Freedom's before and after. They have not even turned one yet and they look nothing like they did when they arrived in May of last year.
Anyways, behold the cuteness. You can also see Nicholas look like a dork. Oh, Nicholas might look quite adorable in these pictures, but there is a reason a gate separates me from him. In fact, I was trying to encourage him to leave the pasture so I could hang out with the other cattle in peace. Nicholas is 2. He is a young, teenage male. He thinks people are play things. He may only be 4.5' tall, but he weighs 1,000 lbs and could easily hurt me. I do not trust juvenile male cattle! I have not encountered the degree of playfulness directed at humans to be as frequent in the female cattle I have met. That is an observation, not a declaration of fact.
