I once had a EE/white leghorn rooster, I first didn't know much about EE and just saw this white beautiful rooster and picked him for my flock
then when he got older he stared attacking me and I asked another EE breeder if I could get a new rooster from her because I needed a new blood in my flock as well (because I found out the EE/leghorn where my hens brother (had same EE mother))
so I asked the other breeder to get new rooster from her because mine was attacking me and she for some reason asked me for a picture of him so I send her this picture and she was like yeah that's not a purbreed EE rooster, this is probably a EE/white leghorn, it's really offten happen that that woman that sold me the EE/white leghorn rooster mix breeds and sell them as purbreed, so I contacted the woman and asked her if she sold me a mixed rooster, and told her to be honest and I would be angry at all, she admitted that she sold me a EE/white leghorn rooster.
now when I look at pictures of EE rooster I can see that he looks totally different from those other roosters so now next I go pick a rooster I will know how he's supposed to look like
I put the EE/white leghorn rooster down few weeks ago because he just got worse and worse attacking me, I would be scared to even come get the eggs so I decided it was time to but him down.
the other breeder is going to give me a purbreed easter egger rooster and some hens this Sumer and I'm really exited for that
