This looks like a lavender chick🤔

[Snugglesandwigglespetcare]

This is a long shot question, but is there any chance some of the eggs were actually from your splash hen? I've heard of at least one situation where a "green" layer suddenly lays "blue", because the brown paint didn't get added on top (blue shell + brown coat = "green" to our eyes)

Also, if you had different roosters with those hens within approximately a month of collecting those eggs that you later hatched, there's a SLIGHT possibility the other rooster could have sired some.

So I have been using this hen in this breeding pen for a good two months now. The chick is definitely lavender. I did have her with my Splash Ameraucana two months ago, but that wouldn’t account for the feathered legs. There has to be some kind of explanation. I’m thinking that somehow someway both the hen and rooster must have a lavender gene in their gene pool somewhere. I have actually bred this hen for 2 1/2 years now and with multiple roosters and hatch many of her chicks. She has never thrown a light chick, ever. Her chicks have always been black. So this is a massive conundrum. The rooster and hen were not hatched by me, so I really don’t know their parentage. The sellers sold them as a BCM and an Ameraucana. I did hatch my F1OE splash hen and I hatched her sire. I did not hatch her dam, so I only have to go by what the sellers told me.

Genetics is just fascinating. I don’t know how everyone can keep track with these kinds of hiccups!!!!

Chick looks blue to me and those eggs look alike to me.
I still say the splash hen is the mother.

Same...

Update…here she is all dried out. I also added a photo of the two eggs that are in this breeding pen. The one on the right is from my Splash F1OE and the one on the left is from my partridge Ameraucana.

This chick definitely did not dry out to be splash or blue. It really does look like my Lavender Orpington chicks but bigger, with muffs, and feather legs and feet

And go!!

Do the two hens lay eggs that are the same shape or are they different? Because the egg colors are similar enough that I think it could have come from the splash hen, like @Not-so Slick Chicken mentioned, sometimes the brown coating has a slight manfunction.

I also find it interesting that the chick looks to have dark feathering on the back of the neck. If lavender, would the color be more uniform? I am really eager to see how this chick feathers out! Be sure to post pics when the feather start coming in!

Just today someone else posted photos of a baby silkie that looked lavender as a hatchling, but the feathers growing out are blue. Here is the thread:

Let us know what color your chick feathers out as!

I'm pretty new to these colors myself. But seems you're much more familiar with them
I have 1 lavender orpington, 2 splash marans, and 1 splash ameraucana. When I received them as 2-3 days old (shipped from hatchery) the splash marans and lavender orp looked literally identical (except feathered feet on the marans)
And the splash ameraucana didn't look anything like the splash marans and was basically solid yellow/white.
Now, the lav orp looks obviously different, the splash ameraucana has color now, and the 2 splash marans.... still look identical (dang, was hoping I'd get different amounts of "splash" on their feathers)

I guess if it does end up being lavender, you'll have proved that your hen and rooster are lavender split and you've just never hit those odds until now. And an unknown number of chicks might be split for lavender.

Perhaps the breeder you got them from, OR the breeders they got THEIR stock from, was messing around with lavenders?

Another angle…left chick is a Splash Copper Marans. Also the two chicks from the splash hen are both blue and all of the other F1OE eggs hatched black or blue chicks. Just another twist

(Excluding the complication of colors that cover up other colors)

Your splash birds should always produce blue offspring, unless they're paired with another blue or splash bird. And your splash chickens will never produce black offspring.

However, if you're getting blue chicks from parents that aren't splash, then one parent has to be blue.
That could mean the blue is so dark it doesn't look blue, or other colors are covering up the blue.

Black x blue = black, and blue
Black x splash = blue
Blue x blue = blue, black, and splash
Blue x splash = blue, and splash
Splash x splash = splash (the color can become faint in this pairing)

Would be easier if colors were consistent and couldn't be mistaken for each other. But where's the fun in that, right?
