Sorry I couldn't get back to this thread sooner, life has a way of getting - in the way a lot.
GaryDean26,
OK! Now I have an idea of it. LOL! But after reading your description all I kind of see in my head is a picture which sort of looks like a Griffin! LOL! Take no offense please. I have never tried to develop a new breed and have absolutely no clue what would be involved. Or how long it would take. I have seen pics of Cream Legbars. I think they are very pretty. Never seen one in person though.
I do have a bird project though where I have tried to improve my flock for the things I like. Some of the items you have listed I also agree with and think are attractive. I have succeeded with some of my birds towards my goals. I also like;
1- Blue coloring with lacing.
2- Black beaks with black or dark violet eyes. Don't like the brownish so much.
3- No comb at all. Like a Dove's head. Skull more upward round that long like a collie dog head. Girls look feminine. Boys like boys.
4- No wattles. No muff or beard. All smooth feathered face. (What do you mean by deep head?)
5- Slate grey smooth legs. (My birds free range the whole property year round)
6- Blue or Mint green eggs
7- Sufficient breast
8- Short back with steep upward curve and short sassy tail feathers
9- Fluffy saddle area
10 thru 14 haven't cared about yet to busy with the above!

15- Four toes
16- No spurs on girls. Only on boys.
17- My boys are larger than my girls
18- Non-flighty and personable.
19- My birds do very well in heat and cold
20- Hearty free range with other livestock, exposed to a lot
21- Mine are tending to be slow to mature
22- Tall/deep? Keel so hatching eggs fit well along either side.
23- Deep and wide for boys, girls should look like girls
24- Assertive hens who will adamantly protect and defend their eggs and chicks. Roo's that will look for danger and protect their flock.
25- Forage (and beg for treats) very well
26- Definitely want broody to preserve natural instinctual and hormonal genetics so it will be role-modeled and passed on.
27- I have two sides to my project going. Muff and beard. And completely smooth faced. Girls looking like girls. Boys like boys.
Foundation breeds.. well, I have EE's with who knows what for a background and some Ameraucana so these would have to do
in that department. LOL!
