We will attempt to discuss both male and female line breeders both in type and color. Since a male line breeding male and a female line breeding female is pretty much the birds that conform to the standard in both type and color not much time needs to be spent on this. Will have photo of them to illustrate the differences of a female from a male and female line and vice versa.
Type (Maleline Female)
First of all No matter which line you are breeding both male and female must pretty much match the standard for type. In the male line breeding female some things can be compromised. Example: Size can be slightly larger then a show female. In the the end she must have Old English type. Some of the things I value are width of breast, smooth topline from head to tails with no abrupt breaks, sound wing carriage and thin straight small to medium size combs with preferrably 5 points. Keeping in mine none are perfect, selection of breeding females will be dictated by the male in the breeding pen. Select females that excell in areas the male is week. Never mate two birds together that have common faults. I referr to this method as compensation mating. In other words you are compensating for the weekness in the male by using a female that is stong in his week points.
Feather quality (Male line female)
This is something that some will tend to overlook. The male line breeding female should hasve a semispread tail that is carried at a 45 degree angle above the horizontal plain of the ground. This is measured at the top feather. The bottom feather should still be above the horizontal. The tail should not be so spread the the bottom feather is below the horizontal. Tail coverts should come up high on the tail. This will help prevent that abrupt break and excessive flush that is sometimes seen at base of tail on males.
Color (Maleline Female)
There is a bit of difference between the maleline and female line breeding femasle when it comes to color. Both are stippled in brown but a show female has much finer stippling on back, body and shoulders. A a glance she will appear lighter and more predomuiantly brown. A maleline female has a much more coarse stippling and will appear darker with much more black showing in feather. Will post photos in a later post of side by side comparison so you guys see what I am talking about. Fronts shoulderrs and bars may show brickish red tints. Stippling on tail may go back further then top 2 tail feathers. Of coarse there is shafting. This can never be totally eliminated in either male or female line But can be minimized and controled. In the femasle line males must have black tails with shafts black all the way down to the skin to accomplish this. In the male line female more shafting can be tolerated and actually have a purpose to be there. On the male line female the hackle can be darker or lighter then desired but really important to be one even shade throughout the hackle with the head a darker red.
Don't want to throw too much at you at one time so guess it is time to end this post. I will end it with a few photos for your viewing. It will show some of the stuff I have discussed so far. The profiles are of a 4 month old pullet that is far from finish but is showing potential. I used her in these photos because breeder selection should start before they are of breeder age. In this way you can cull the lesser ones and make room for the good ones. The photos of sections by color are of actual breeders.
