I want to start out by saying that I hate questions like this - because whenever I tend to answer them - people get upset and offended at me. I tend to give them the same answer I would give to a breeder if we were standing side by side at a show looking at bunnies - without factoring in the emotional aspect of "this is their pet".
Then I hear the "well...I'd rather have a friendly bunny or a cute bunny than worry about X, Y or Z".
I say all this to say - I'm going to take your question and answer it as if I was talking to a breeder who was looking at your rabbits and deciding whether to buy them for show. I'm going to give the good points and the bad points and not mince words. But by my answer - I'm not saying that your rabbits are or aren't good rabbits - I'm not evaluating their "worth" as a bunny. I'm commenting only on how I feel they would do on the show table in my area.
Ok?
I like the head shape of the lighter colored bunny on the far left in the last two pictures. It is not as rounded as the head shapes are going towards now...but it isn't the older style wedge shape either.
I like the balance of the ears to the size of the rabbit. Nowadays the ears are going to more of "cat-like" ears rather than the longer "mule ears" as I call them. I will be sharing pictures to show what I mean in a minute.
As far as their body "type" - it is hard to see their quality. I like short-bodied lionheads that tend to sit upright because they are so short. The longer bodied rabbits tend to lay like your rabbits are laying. Once again - I think you'll see what I mean when I show photos.
My biggest concern is their mane - or lack thereof. I can see the mane - but it is not full and dense as it should be. I suspect they are single mane lionhead (mixes). From what I can tell - the rabbit in the second picture should keep his/her mane because it looks like the wool has a crimp to it. If the others have a crimping to the wool in the mane - they should keep it when they molt.
When I was starting out - I did show some rabbits with the same type of mane and the comments I got were that the mane was not dense enough and those rabbits never did as well in the shows as other rabbits.
Now - I haven't done a lot of shows - maybe 6-10 or so....but in each show - usually with 15 or more lionheads - I have taken either BOB, BOS or BOTH in the same show - against 3-4 other competitors.
Based upon the comments judges have given me - I have an eye for type (my mentor trained me for this) and the judges have usually chosen my "typey" rabbits over the ones with the fuller manes - but not always.
It is also important to remember that each time you show - you are basically paying for that judge's opinion on that particular day on that particular rabbit in that particular condition. I've shown in double shows where I won BOB with a rabbit that was DQ'd in the next show by another judge. The DQ? "The fur is too soft". Seriously - the first judge loved the soft wool/fur - the second judge felt it was too soft even though they loved the rabbit's coloring and mane and felt like if the fur were a bit coarser - the rabbit would've taken BOB.
Now here are some photos of rabbits you may want to see:
In these first two photos - notice how upright the rabbits sit:
This is what I look for when it comes to type - here is another example:
Pow Wow had an excellent combination of mane and ears and type in that photo.
This is a longer lionhead posing - you can see more space between the table and its belly - but notice the wonderful mane:
Here's another longer rabbit - but notice the mane and how dense it is:
Finally - look at Cocoa's ears - the shape and size...this seems to be what many judges and breeders are going for now...
I am going to post this before my computer shuts down on me - and then add some recommended links if you want to learn more about lionheads.
Please understand though - it seemed as though you were asking me what was good and bad - and so I went beyond the "cute lionhead" I would normally do for someone asking - because most people don't want to hear all the details.
