Loveourbirds, would like your opinion on my plans. Now mind you I'm starting out with a choc split (which is a cockerel) and the 4choc AM's so my stock is limited. These are 2nd generation. They were a split cock over chocolate hens.
Plans are pick the best choc or split cock and put it over my pure black AM hens to help continue with type and lessen the chances for single combs and clean face chicks. My intentions are to do this for 4-5 generations each time keeping the best cock and then try to keep some pullets and the best cock from that batch. Sound like a decent start? Any suggestions, ideas?
keep in mind i havent worked with the chocolate gene, so its safe to question any of this advice.
if i am reading this right you have one rooster with split chocolate gene, and 4 hens with a 75% pure line (split over full)
my method for this would be as follows:
due to the two sets of splits, i would breed the rooster over all 4 hens for one full season (i call 4 months a season). pay attention to what offspring comes from what hen. 2 or 3 of the hens should be full chocolate, with 1 or 2 being split. by doing this, you should come out with a good percentage of chocolates. keep your best original pair for "just in case reasons"
keep your cockerels from the more pure line, as the cockerel blood will have more influence on the line. look for the very best 2, type and color. breed these over hens selected half and half from the split lines and the full lines. keep a couple of the darker colored hens in the mix intentionally, black if you have them. use hens of the best type, dont worry so much about color on them yet. make sure your combs, eye color, and leg color are right. with this breeding i would use 1 rooster to about 4 hens in 2 groups (10 total). from this breeding you should have several "excellent" breeders.
from the previous breeding, hold some excellent roosters and hens, at a ratio of about 4-6 (maybe 5 chocolate and 1 dark) hens to 1 rooster. their breeding should yield excellent chicks with few culls. you will never breed a line that makes 100% show chicks, it just cant happen. if you can get 1 excellent show quality out of 10 you are doing great.
if i understand the chocolate gene correctly, i would cull any that are to light in color- and always breed for a few "extra dark" ones to mix in with the breedings.
additional note - when i say cull, it does not always mean to kill them. someone somewhere may want what you have extra to start working with their own flock. just dont sell them as "show birds".
