Yes, that would be a good procedure..F1 females to their sire. You could also breed your best cockerel to his mother.
There are several threads in both the Exhibition and the Breed sections on Wyandotte. Post photos and ask lots of questions....many folks here are more experienced than me.....
I can only tell you what I do when determining a keeper or a cull.
Out of 100 chicks you produce, you might only select 5 - 10 pullets and 2 - 4 cockerels at 12 months....
Notice I'm not including color variety until 8 months. Unless you are starting with good breeder stock and not crossing colors.
At 4 months, you can see the comb well enough to determine if it will be a proper structure or inverted or single.
The head should be wide with no crow headed.
Look at leg stance. and motion...no bowed knees or knock knees. feet should be proper with no curled toes.
The back and breast width should be smooth and wide.
Check leg color...it should be a nice yellow.
You can weigh the birds and see if any are lagging behind the average weight.
Begin looking at carriage or silhouette.
Process your culls as fryers or broth.
This is a good time to number band your birds...so record keeping on each bird can be accomplished.
At 8 months, the silhouette will be very visible.
Acceess the body carriage, head shape, combs and eye color.
Tail angles are more defined.
The pullets should have a nice wide and full tent to their tail. You should be able to gauge the width of the pelvic zone for egg laying ability. between the end of the keel bone and the pelvis, you should have enough length to accomodate the internal organs and the egg laying process.
The cockerels should have a nice carriage that will hold the muscling that comes with proper growth...good leg stance, width of frame and evenness of keel.
Check the wings for full primary and secondary feathers with no splits.
Again weigh your birds and note the ones that are not gaining as they should.
Leg color and combs should be properly developing.
Begin looking at your color.
Some birds will be first string and some will be labeled second string. The culls can be sold as layer replacers or meat birds.
At 12 months, the body structure should look like the Standard and weights in the range established in the SOP.
They should have molted and are showing the proper feather structure both in down and surface feathers.
Pullets should be laying by now and should have a nice sized off white to light tan egg. There should be a nice spread in the pelvic zone...I like to use a three finger width guide. Their back line from the cape to the tip of their tail should show the proper angle.
The cockerels/cocks should be filled out nicely, gait is good, good heads, nice back line, proper tail angle and sycle feather length.
Attitude should be inquisitive, calm, energetic. Food conversion should be very apparent...you want plump but firm muscling
Select only your best birds to the Standard in your breed pens. Keep good records on each bird.
At 18 months,
Aggressive cocks should be noted because this can be hereditary. Only use as a last resort even if he is an excellent bird.
Laying production should be 3 - 5 eggs a week during laying. Hens should show some desire to brood.
