I have 11 week (purchased as chicks, so more like 12) that I need some feedback on. I'm pretty sure the Buff Orpington is a hen, but the jury is out on the Black Australorp. Now we're starting to wonder if the RIR is a roo as well? When we got them as chicks, we guesstimaged them by size and development with RIR as the oldest then BA and BO. They're coop bound in a week and I'm keeping my fingers crossed that the BO isn't going to be the only hen we're left with. I wanted to get better pics but they were not enjoying the flash too much. Here they are at about 5 weeks. The BA has quite the tail which is why we think it may be a roo, but it's not always standing up. Here they are taken last night at 11 weeks. There's that tail again... lured with treats only to be flashed... Back view of RIR Couple more views of the RIR Thoughts?
