Crossing Questions

[Demosthine]

Hello All. About two weeks ago, we completely confirmed that our Partridge Silkie is a cockerel. He is significantly larger than our Splash Silkie, sits very upright with longer legs and just started crowing. I'm not sure he'll be able to mate with anything other than our Splash, so I'm not particularly worried about his crossing.

We also have a Black Copper Marans and a New Hampshire that are almost guaranteed to be a cockerels. Now, we have two Barred Rock hens and a Birchen Marans that are laying. We also have two Black Copper Marans and two New Hampshire pullets that are not laying.

Breed Hens Cockerels
Barred Rock 2 Hens
Birchen Marans 1 Hens
Black Copper Marans 2 Hen 1 Cockerel
New Hampshire 2 Hen 1 Cockerel
Silkie 1 Hen 1 Cockerel

Now, if my understanding and reading is correct, I can have the following crosses:

New Hampshire over Barred Rock --> Black Sex Link (Light Brown Eggs)
New Hampshire over Birchen --> Black Star? (Medium Brown Eggs)
New Hampshire over Black Copper --> Black Star? (Medium Brown Eggs)
New Hampshire over New Hampshire --> New Hampshire (Light Brown Eggs)

Black Copper over Barred Rock --> Black Sex Link (Medium Brown Eggs)
Black Copper over Birchen --> ? (Dark Brown Eggs)
Black Copper over Black Copper --> Black Copper (Dark Brown Eggs)
Black Copper over New Hampshire --> ? (Medium Brown Eggs)

This is mostly just my own curiosity. I do not plan on selling them as a true breed, if we end up keeping the cockerels at all. That depends on how loud they get and how well my neighbors tolerate them. From my understanding, though, they should all lay large brown eggs. The Marans cockerels should cause a darkening of the egg color, while the New Hampshires will lighten it, right?

I haven't found any good resources for this type of thing. I know none of the offspring will be any type of recognizable breeds except BCM/BCM and NH/NH. Thanks for the information.

Breed Hens Cockerels
Barred Rock 2 Hens
Birchen Marans 1 Hens
Black Copper Marans 2 Hen 1 Cockerel
New Hampshire 2 Hen 1 Cockerel
Silkie 1 Hen 1 Cockerel

Now, if my understanding and reading is correct, I can have the following crosses:

New Hampshire over Barred Rock --> Black Sex Link (Light Brown Eggs)
New Hampshire over Birchen --> Black Star? (Medium Brown Eggs)
New Hampshire over Black Copper --> Black Star? (Medium Brown Eggs)

Black Copper over Barred Rock --> Black Sex Link (Medium Brown Eggs)
Black Copper over Birchen --> ? (Dark Brown Eggs)
Black Copper over Black Copper --> Black Copper (Dark Brown Eggs)
Black Copper over New Hampshire --> ? (Medium Brown Eggs)

assuming the ones listed on the left are males and the ones listed on the right are females

New Hampshire over Barred Rock --> Black Sex Link (Light Brown Eggs) Correct
New Hampshire over Birchen --> Black Star? (Medium Brown Eggs) golden birchen males/black copper looking females

New Hampshire over Black Copper --> Black Star? (Medium Brown Eggs) Black copper maran looking birds
New Hampshire over New Hampshire --> New Hampshire (Light Brown Eggs) correct

Black Copper over Barred Rock --> Black Sex Link (Medium Brown Eggs) Black Hens and Barred males
Black Copper over Birchen --> ? (Dark Brown Eggs) Black Copper maran hens and Golden Birchen Males(Birchen looking untill the male's hormones start kicking in, at that stage their silver hackles start turning into lemon looking hackles and saddles)

Black Copper over Black Copper --> Black Copper (Dark Brown Eggs)
Black Copper over New Hampshire --> ? (Medium Brown Eggs) Black Copper Maran looking birds of both sexes



intersting fact is Black copper maran roosters over Birchen maran hens will give you genetically Sex links chicks...But since both hatch black with cream underbelly its impossible for you to tell them apart

Yes, the breeds on the left are the males and the right are the females. I thought I read somewhere that when you list the cross, you always put the male first, or male over female.

Thanks for the information! Genetics always got so complicated for me. That really is an interesting fact there at the end.
