If they were all that combo none could have rose combs and many do... especially those from Hoovers, so they must use a different mix(RIR and SLW are also used by some)? ISAs however are usually from RIR/RIW)
July 1 2021 hatches. Friendly little dudes, just already have 2 adult roosters and not enough hens. Moms were Cackle Lavender and Black, dad was a Cackle Lavender. My broody sexlink hatched 4, we hatched 4 in an incubator. https://www.lsn.com/poultry/blue--lav-ameraucana-roosters/6678347.html
They both are red sexlinks yes, but from a different hen/roo pairing. Queens typically have darker feathers like black in some areas including the tail(some may also have rose combs but not all). ISA however will be brown/red and white, no black and will have single combs only.
Ameraucanas will always have beards/muffs, dark legs and a pea comb. They also only come in 9 colors, none of those weird EE patterns you see(though colors can vary if you breed one color to another). This site is helpful and has descriptors and photos...
if a true ameraucana (not EE or Americana) you have a better chance of this if the sexes were reversed...blue egg male with brown egg female...will always be olive laying chicks
I say hatch 2x as many as you want...some wont be fertilized, some just wont take and some that do quit for no apparent reason. I started with 17(I found a crack in one upon arrival) with 5 under broody, the rest in the incubator.
Near Cookeville TN....I had never hatched either but we did hatch 4 of these, broody hatched other 4, and let her raise them all. We did both just in case she didnt sit the whole time, never had a broody, wasnt sure how it would all work out.
I was able to get my hands on some actual Ameraucana hatching eggs locally this summer when I had a broody sexlink hen and we got 8, they are adorable...Blue, Lavender, and Splash.
Yes I hate that! It is even funnier when they argue the fact and you can look and see that the hatchery doesnt even breed them... if you go to most websites they do say Americana, never Ameraucana(like TSC/Hoovers below). Now just adding to the confusion they are selling easter eggers as a whole...
Yes you would get sexable chicks. I will be doing this with my Blue Ameraucana Rooster and my Dominique and Cuckoo Marans hens to hatch sexable olive eggers next year.
