I just hatched a clutch of eggs containing 4 olive eggers(BCM X EE) I have read various articles that seem to conflict on how to sex them. Some say spot on head some say pin feather length, tail development, down color, etc. I imagine that the answer is it depends on the parent stock since it’s a mix breed not a true standard breed.

Anyway one of the 4 eggs hatched 2 days ago still waiting on the other 3 but starting to lose hope not seeing any progress or hearing any chirps. My wife has really fallen in love with this one and will be heartbroken if it’s a male. We already have more cockerels than recommended but they a still young enough that the hormones haven’t hit them real hard yet so they are playing nice for now.

8 week update and I’m happy to report no surprises. Comb and wattle color is still very pale. Feather color is quite nice with no signs of the red shoulders and backs like her black copper marans 1/2 brothers. Im really liking this chick now just a couple months more waiting to see what color eggs she will lay.

X3 Pullet-very interesting coloration, would love to see her pics in about 6-8 weeks from now.
Here she is 6 weeks later. She is 12 weeks old and I think it’s safe to say she is a pullet. She has been named “blue”. I’ll try to remember to update this thread one final time in 2-4 months or so once she lays an egg.

The head spot thing only works if it's a non-barred male over a barred female. In that case, males will have head spots and females won't. But that doesn't apply with your chicks. Feather sexing also doesn't apply. That has to be bred for specifically and really the only variety I know of where is works is with Amderlinks. Tails also are not a good indicator of sex when they are young. So you will need to judge by their combs, size and redness. 6 weeks of age is a good time to start with that.

Update, she is now 7 months old and laid her first egg today. She was apparently working on laying it in the corner of the coop when I opened the door to fill the feed. I must have scared the egg out of her because she jumped up and ran and out it came. Unfortunately it cracked when it hit the floor. I’m very excited about the color.
 
I imagine that the answer is it depends on the parent stock since it’s a mix breed not a true standard breed.

Yes, it depends on the breed mix. Certain mixes can be sexed one way, others can be sexed a different way, and there are plenty of mixes where you just have to wait until they show some obvious trait (like red combs or crowing.)

I just hatched a clutch of eggs containing 4 olive eggers(BCM X EE) I have read various articles that seem to conflict on how to sex them. Some say spot on head some say pin feather length, tail development, down color, etc.
Assuming BCM is Black Copper Marans and EE is Easter Egger:

With BCM father (no white barring), then if the EE mothers had white barring you would have one kind of sexlinks (head spot on males, not on females.)

If the BCM father had fast feathering (which is likely) and the EE mothers had slow feathering, the chicks would be feather-sexable.

The BCM father has the gold gene. If the EE mothers have the silver gene, the chicks will be gold/silver sexlinks (sexable by down color.)

But unless you know something about the EE mothers, you are stuck with guessing. And it is common for EEs to have no barring, fast feathering, and gold color-- which would produce chicks that are completely unsexable by any of those methods (all chicks would have no barring, fast feathering, and gold color.)

If you get any chicks that DO have white barring, or silver color, then they are definitely males (because the father does not have those those traits, so they must be inherited from the mother, who gives them only to her sons not her daughters.) If a chick has slow feathering it is probably a male as well, but I can't be certain because of how feathering speed is often ignored when selecting breeding stock.
