It's not only TSC, I got some hatchery chicks from our Rural King and bought some of what I thought were Brown Leghorns that I had been looking for a breeder for some. There was a tub with some chicks that were marked Brown Leghorns and since I hadn't been able to locate a breeder, I bought some. They turned out to be Partridge Rocks. Leghorns lay white eggs. I sold them because I wasn't planning on working with another breed. I did get some Rose Comb Dark Brown Leghorns from a breeder.TSC gets their chicks from Hoover Hatchery.
The TSC staff are notorious for mislabeling their chicks and not knowing one breed from another. It’s pretty ridiculous sometimes.
Some hatcheries call them Ameracaunas.
But they’re actually EE.
What’s the difference?
Ameracaunas are not a mixed breed and will always lay blue eggs and will be sold as specific colors; wheaten, black, blue, splash, white, etc.
Easter Eggers are mixed breeds that have some Ameracauna genes so they lay various colored eggs. Usually some kind of blue or green but sometimes brown or even pink looking ones.
They can’t be sold as specific colors since they’re mixed and there’s no telling what they’ll look like when they feather out.
Do you have pictures of your birds you can post?
