I have some strange mutt brahmas. They are the offspring of a buff brahma cock over a light x dark brahma hen. ( i bought them like that as my very 1st chicks. The cockerels are colored like lights and pullets are buff colored. Anyways i got a bator and hatched 1 of the eggs. Any ideas on what it will look like. Its still wet but it looks like a dark brahma color now
You say your males look like lights. If you look close, do they have some brassy/straw ting to their hackles (neck) and saddle feathers ? I'm betting they do, and basing this answer like they do.
Being the result of a gold / silver breeding all the male chicks would be split gold/silver, (possessing one of each) The pullets out of that same breeding would be the color of their sire, gold based (buff in this case)
Now breeding these chicks together, the females only contribution will be in helping determine what color the male chicks are, as the female chicks will be determined by their sire. Now your male being split gold/silver will throw both silver(light) and gold(buff) pullets.
The male chicks can also receive either a gold or silver gene from Dad, Being that in this case Mom will be only throwing gold (buff), if it meets up with a gold from Dad, you will get a buff male chick. If Dad throw a silver, along with Mom's gold you will end up with a split gold/silver male, like Dad.
When you have a split gold/silver male it has been my experience that the silver(light in this case) is much more apparent, the gold only giving hints it is in there by the brassy hackle and saddle feathers. Female having only one color base gene are either gold, or silver.
So now that I probably have you bored to tears, you will get light and buff pullets, buff cockerels, and split gold/silver cockerels. What you will not get is pure silver (light) cockerels.
The wildcard in this scenario might be pattern, the Columbian pattern of both the lights and buffs tend to dominate over the penciling of darks, so columbian should be the prominent pattern in your chicks, but depending how smutty (extra dark markings, most often on back) your hens have, there is the outside chance you could get some chicks with some degree of penciling.
There may also be some variation in the depth of the buff color seen as well.
