I have a Westclox battery operated wall clock with chicken on face. The battery is new. The second hand tries to move but just "clicks" How can I fix this?

Check that the hands are tight and also that they are not touching. and jamming. Remove the battery and replace it. Some have a lever to give it a jolt to get moving.

put the smallest one on first and the longest one second

no chance to remove the box
it is held in place by a nut on the spindle shaft from the face of the clock under the hands

The whole front square face of the clock has 4 little nails which are located in the middle of each side (inside and next to the edge of the joint), so you have to carefully insert a screwdriver and lever the front out. After this you have to remove the hands (remember to set the clock and alarm hand to 12:00 before taking those away). The face will be loose, and you'll have access to the mechanism. Clean the alarm contact (look for a double silver metal arm that touches an small bronze stick. Alarm button can be release by gently lever the little nail that shows in the center when button is up at clock's backside.

Westclox clocks--and, at one time, watches--were once made in the United States. However, especially since the purchase of the Westclox brand and assets by a holding company in 2007, and the general disorganization that followed that acquisition, it's likely that all production has been moved offshore.

From about 1919 through the early 1980s, Westclox products were also made in Canada at their factory in Peterborough. Westclox also had a large factory in Scotland that manufactured over 50 million clocks between 1948 and 1988.

These are general quartz wall clock instructions as I dont know enough about what type/style of clock you have.

Open the access door to the dial and hands of the clock if required. Some battery-operated clock movements are sealed inside the clock case with a back panel that is screwed in place. To gain access to the hand set knob, remove the back panel screws using the appropriate tipped screwdriver.

Turn the minute hand (or turn the hand set knob at the rear of the movement if access is available) carefully counterclockwise or clockwise until the correct time is reached. Keep in mind that using the hand set from the rear would require turning the knob in a clockwise direction in order for the hands to turn counterclockwise.

Move the hour hand carefully with your fingers near the center of the hand to the hour that the clock is striking if the striking chime is not counting the correct hour. The hour hand is a friction fit hand and will move without engaging the minute hand.

Replace the back panel and tighten the screws with the screwdriver if removal of the back panel was necessary to access the hand set knob.

Close the front access door if required.

Usually these clocks are assembled using clip-on type of assembly. Sometimes metal staples, pins or clips are used. You have to unbend or extract these(depending on what type of clips are used). If clock parts are made oft brittle plastic, it may crack,so, you should be carefull.
If the clock hands came off, try to find out if you can get the glass off without dismantling whole clock.
Hands mostly are friction fitted (push-on).
To align hands correctly, pull them off hub and then push them on pointing exactly at 12 o'clock.

If you are sure the hands are not touching as they pass, perhaps the minute hand and hour hand are binding together at the hub. Try this: Gently pull on the minute hand by gripping its hub with the nails of your finger and thumb. It should slide forward a little (or come off). Also the same for the hour hand, to ensure it is not binding on the face of the dial.
I don't know the particular clock, but if it has a SECONDS hand, this is often the one that needs to be freed.
If all the hands are free, all should be good. If it has a seconds hand and the clock stops when this hand is going "uphill", try a fresh battery. If this doesn't fix it, remove the seconds hand and use the clock without it. Or you could try to counterbalance the hand by adding a little weight to the opposite side... this could work, but as it increases the mass of the hand also, it still might be a problem.
Another way might be to shorten the seconds hand..!

Try setting the crown to position 2 - i.e. the position normally used to adjust the date.  Then use the top and bottom stopwatch buttons to adjust the minute hand and 1/10th hand respectively.
