Interested in knowing what sex you think my 6 Lavender Orpingtons are; I determined pretty early that number 1 is a roo. His wings, tail and stance are very different then the other 5 which I am hoping are pullets. Number one has just a tiny round fluff tail while the other 5 have very noticeable tall feathers growing. What do you think? This is my first baby chicks. Our first chickens turned 4 months old yesterday; 2 Buff Orpingtons and 2 Black Austrolops.
