Hi, I got my first two bunnies a few months ago. Two does.  They were  born on December 26, so they are about 4 1/2 months old.  They are not very cuddily and hard to catch.  I wouldn't call them "tame."  Is there still hope that they will get tame?
 
I don't know the breed.  They are not lop ear.  One is brown and look like peter rabbit and the other is black with some random white hairs.  They are litter mates.  They are large and long.  Sometimes they growl if we are trying to pick them up and one nipped my granddaughter (9 years old).  Once I pick them up and sit and scratch their head and talk to them, they seem fine.  I'll post some fotos later.  They live in a big hutch in the middle of my fenced chicken yard and sometimes I let them out during the day and always put them up at night.  I leave the hutch open when they are out for them to go in when they want to. 
 
Some questions:
 
1.  What can I do for them to be more tame?
 
Try bringing them one treat each, maybe one or two a week. Bring them inside if they aren't already, so that they are more used to human presence.
 
2.  Should I have them fixed?  I do not plan to breed them.
 
Yes. Fixing will help with their hormones, and if they meet un-fixed males, there will be no oops litters.
 
3.  They "hump" each other in a very serious way sometimes, is that normal?
 
They are trying to establish domanince, but get them fixed, because one of them might be a boy.
 
4.  Would getting them fixed make them sweeter?
 
Genarally. It will help control their emotions.
 
5.  Will they get better about us catching them when they are older or fixed?
 
Yes, but that may take a while. When you try to catch them, walk calmly, so you don't scare them. It is possible to scare a bunny to death. Please don't give up on your bunnies.
 
Thanks to all you rabbit people.  I really love my bunnies.  Their names are Rosie and Lulu.
 
 
I'm glad you love your bunnies! They have great names! If you have any more bunny questions, please PM me!
