This is a 10 week old Lavender Orpington. I am suspicious about it being a roo because the tail feathers coming in are a bit less straight than the other pullets. They are starting to look a bit like sickle feathers. The comb and wattles look pretty similar to the others. Still more yellow and definitely not as large and red as some pics I have seen online. It is also leaner and not nearly as fluffy as the others and the feathers around the neck also seem to be swirling around the neck rather than just laying flat and straight like the rest of the fluffy girls. Any thoughts? I have never had birds this young so I have never had to sex them! Thanks!!
