GCR Marans

GCR Marans Colorado based breeder of private line Black Copper Marans. NPIP Certified/Avian Flu Tested.

We are private, family owned breeder of Black Copper Marans (BCM) located on the front range of Colorado. Our History - In 2019 we discovered this amazing breed and were captivated by the stunning dark eggs they produce. We purchased our very first Black Copper Marans chicks from an unnamed hatchery. When they began laying we were rather disappointed in the quality of egg color with the vast major

ity of eggs at or below a #6 on the Marans egg color chart. After much research and reading we learned that the dark egg trait was something that required significant upkeep and generations of selective breeding is necessary in order to keep the egg color quality high. From that point on, we made it our mission to build our own flock to improve blood lines so that our birds would lay the iconic dark chocolate eggs. We began sourcing hatching eggs from the private breeding community for better blood lines and have collected and combined multiple lines from across the United States. Breeding Strategy - Our breeding method is specifically based off of selective breeding. We do not believe in inbreeding and/or line breeding to achieve the desired traits, and feel that it's not healthy for the birds to impose any form of inbreeding. We apply two main techniques: #1 the "Law of Large Numbers" - collecting and combine a large number of birds from various flocks, and #2 stringently selecting breeders based on egg color first and SOP second. With this method, we are able to target the specific genes and traits that are desirable while avoiding inbreeding, instead of forcing specific genes and traits by inbreeding.

Well folks, it’s probably time to share the bad news. Unfortunately, due to being overly busy with work, we’re not going to be offering chicks this spring. It’s unfortunate because we’re really getting some gorgeous eggs this year. I hope that we will have more time this fall for fall chicks.

The good news is that our flock isn’t going anywhere. We’re still keeping up our breeding program and our mission to continuously better or bloodlines.

Keep following our page and when we do have availability again, you’ll be the first to see it when we get a post up. Cheers!

This 2026 flock is off to a great start!

Update: They've all been picked up.

FREE - to any home!

We have 7 Black Copper Marans roosters available. They are all culls and would be terrible breeders for Standard of Perfection purposes. However, they would be excellent breeders for egg color or for crossing to make olive eggers. They are young and all hatched between May-July 2025.

MUST TAKE ALL 7!!!

UPDATE: Only roosters/cockerels left, the pullets are sold out.

Great news! Black Copper Marans pullets are finally available!

To all of you who have been asking, sorry for the wait. Life and work has been extremely busy lately, but we now have some time.

These girls hatched between May-July 2025 and are just starting to lay - and the eggs are gorgeous. They are bred specifically for egg color. Though they are beautiful birds, they will not meet SOP standards and are not recommend for showing - mainly for feather coloring.

8️⃣0️⃣/each. Minimum 2 pullets. Cash only. First come, first serve. No deposits necessary. Pick up 12 miles south of Franktown. Cockerels available for 3️⃣0️⃣/each or free with purchase of 4 or more pullets. Please message for more details.

Just another example of how important selective breeding and genetics are for Black Copper Marans, and the results of mass production....

I came across this post from Cackle Hatchery with a photo of their Black Copper Marans eggs that I thought I'd share. Notice how most of the eggs wouldn't even make the color card - and by Bev Davis's standards, they shouldn't even be considered Marans if the egg color isn't a #5 or greater. Of the nearly 300 eggs that I see in their photo - I can maybe count 10-15 eggs that would qualify as #5, and ZERO eggs of a respectable #7 or higher.

Just to clarify, because I’ve already gotten a message. When I say “cull”, I don’t mean kill.  I simply mean removed from the breeding flock.

Good day all! Just a quick availability update. Unfortunately we're not going to be offering fall chicks this year. Life is busy and time just doesn't allow.

However, later this winter we will have 1-1/2 year old hens available. These are our 2025 breeder flock that have laid all the deep dark eggs posted since January (picture included in this post). We are letting these girls go to make room for the 2026 breeder flock.

For those of you who will be interested in these hens, please keep an eye on our page for the availability post. We're not going to be taking reservations or deposits for these hens, it will be first come/first serve when they're available. These hens go very quickly, so be on your toes!

Have a great day!
