We bought four Black Australorps and four New Hampshire Reds from TCS almost three weeks ago. Right now they are all losing their fluffy feathers and most have grown more chicken-y looking feathers (the NHR have lost almost all the fluffy chick feathers and the BAs have started but still are holding onto them). I have read that you can sex chicks by tails and wings. We have two chicks that have long and prominent tail feathers and my wife and I figured "oh those have to be roosters!" I did a little Googling and it seems that we might be wrong and that those might be hens-- which means we might have two hens and six roosters. Obviously that's no good because we want hens only. Is there a definite way for me to figure this out? Right now I'm concerned we have a flock of roosters and that I'll need to start all over again with new chicks.
