You need the services of a gunsmith. There are about a half dozen or so reasons if not more.
You will have to tell us if they are loaded or empty, whether they are shotgun shells (and the gauge), rim fire or center fire and the caliber.
I have a Winchester 16ga model 1400 I got it a few days ago I cleaned it and went out to shoot it but it does not want to eject the empty shell, what could be the problem, anybody?

Yes, there are as well as people who collect other types of cartridges. Both the loaded type of shotgun ammunition and the empty 'hull' of a shotgun shell. If it exists, there is probably someone who collects it.
The moon is very big about 1/4 of the size of the Earth (it looks small because it is a long way away). The moon is also solid (like the Earth) and thus there is no room in it to be filled up with shotgun shells. If the moon was empty then you would have to turn 1/4 of the Earth into shotgun shells to fill the volume the Moon takes up.
No, to reject is to exclude from consideration when considering whether or not to select something. The object does not need to be physically manipulated in any way. To eject something is to physically throw it out of whatever it is in. Empty shells can be ejected from guns. A bag of garbage can be ejected out of your back door.
Empty snail shells.
With the gun pointed in a safe direction, safety ON and your finger OUTSIDE the trigger guard, press the disconnector (to the left of and to the rear of the trigger) Pull the forearm to the rear. The chambered shell should extract and eject. If there are more shells in the magazine, they will load into the chamber when the forearm is moved forward. You will need to repeat until gun is empty. Now- go contact Winchester Customer Service through their website, download and PRINT the user's manual- which gives instruction on this)

If it's doing it regularly, it may be an extractor problem.
Most hold ammo in tube under the barrel. Make sure firearm is empty then unscrew the end cap on tube/magazine. Plug should be there.
