I agree, the first two breeds listed are the same. Americana = Easter Egger. The third listed, salmon Faverolles, is a totally different and separate breed.
Many hatcheries sell Easter Eggers and label them as Americana. Some hatcheries sell Easter Eggers under both names.
I find it quite dishonest and a little insulting actually.
Anything to make more money I suppose.
I find it a bit insulting too.
Mostly that the AmerIcana (with an I) gets people looking to buy AmerAcana (with an A) while the ones with an I are certainly not the same as the actual ones with an A.
Then toss in there the name similarities to Aracauna (pretty sure I spelled that wrong ).
Basically there are a lot of birds being sold with different variations of the name catching folks off guard, causing confusion and getting people to buy what amounts to Easter Eggers when they were looking for something else.
