My leghorn is not short and squatty like this chicken either.. Mine is thinner built and is legger and is built different.
To me, this chicken doesnt scream "leghorn"
But Im by no means an expert:)
Not a leghorn looks nothing like the one i have. They also have big floppy combs.
EE mix? First think I thought when I saw it was looks just like my EE minus the dark legs. :)
