RIR X Light brahma

[tinyhillfarm]

Hi all. Hoping you can help me out. I just hatched some RIR /LIGHT BRAHMA chicks.Father is RIR,Mother is light brahma. i heard they can be sexed at hatch. yellow male. dark brown/black female. Is this true.? anyone have any experience on this one? everything i have read online does back this up. but not sure i can trust what i read any ideas? If you hace an pics from your own hatching please share. thanks

No pictures but it is almost true. This one is based on science, not just something you read on the internet. Read the very first post in this thread for the science.

The reason it is almost true is that the black is wrong. A RIR rooster over a Light Brahma hen will produce a Red Sex Link. Males will show yellow and females will show red. Black has nothing to do with a Red Sex Link as far as determining sex. That red can be different shades of red too. Some crosses will give you a dark brown but some give you a fairly light reddish color, sort of a buff. It could be many different shades of red. Instead of saying dark brown/black in your statement, say reddish.

Some sex link crosses will produce solid yellow or red chicks but some will produce chicks that are only yellow or red in certain spots. It helps to have those chicks side by side to compare them. I have not done your specific cross but I’d expect the chicks from that cross to be pretty solid red or yellow and real easy to tell apart.

You can try browsing through that thread I gave you above for pictures of red sex link chicks. It’s a real long thread and I don’t know if anyone has photos of your specific cross or not. But if the rooster is a pure RIR and the hen is a pure Light Brahma, you have red sex link chicks.

Ok, here are some pictures of my three Rhode Island Red x Light Brahma crosses from today (May 30th) at 12wks old. I'm positive they are pullets - albeit weird looking ones, probably due to the cross they are. They are dark gold/orange-ish with black tail feathers and black markings around their necks, like their mom who is a Light Brahma.

Is your Brahma a light Brahma rooster? I just had 3 chicks hatch yesterday and they are yellow and no markings but they all have hairy legs feathered legs. So probably came from rir hen. Not the black sex link hens Lol. Got a lot of questions to ask. May be a little whitish in other pics.

Yes my silver sebright went broody and hatched everyone else’s eggs. Lol.

What if the rooster is pure light brahma and the hen is pure RIR? Would that still create a red sex link? Sorry I was doing some research because I hatched something I'm unsure of and my only roo is a light Brahma. I have RIR hens and a drank brahma hen but I don't know which hen laid the eggs I put in the incubator

Unfortunately, no. That cross would produce silver pullets and golden (silver/gold) cockerels. On hatch day, they would look pretty much the same. The mahogany may mess with the results, but I could only see it making it harder to tell the pullets apart.

The best way to remember how the sex-linked crosses is to think of red sexlinks. Flip the colors to find the genes needed for the parents.

Great info. thank you for the link. I guess the black coloring is wrong.Maybe my RIR is a mix. Don't know. was told he was pure when i got him. So knowing this they may not be females. only other way is to check the vent to determine .The article was both helpful and confusing. But i get the point. would vent checking work at this point if they are only 2 days old?

i put them under light last night. oooooh ya no brown or red here. all black with patches of white . DAD
MOM

I can post pics of chicks. will need to go take a picture.

The basics of making sex linked chicken is fairly simple. The father gives recessive genes to both his sons and his daughters. The mother gives her dominant gene to her sons but gives nothing to her daughters. So at hatch the males display their mother’s dominant gene and the females display the father’s recessive gene. It took me a while for that light bulb to come on but once it does the basics are pretty simple. It’s putting it into practice when it becomes more challenging.

I’ll wait until I see your photos for any more comments, but looking at the parents you should have sex links.

Ok, sorry this took so long. Duty was calling at work . Here are pics of both

Sorry pics might be blurry. See what I mean about the black. I have people taking the girls. Now I'm afraid to let them have then .since they could be boys ...geeeez
