I was fairly confident that we had a hen, but then I read the huge thread on identifying the sex of Rhode Island Reds and now I'm freaking myself out. We recently had to re-home our beloved leghorn because "she" turned out to be a little roo. We had him for 2 months and loved him dearly, so it was very hard on the family and has me paranoid now. I our RIR is 7 weeks old (we got her March 16th and she was newly hatched) and she had a very distinct stripe on her head. She has never shown any anger or rooster-like behavior. When she was younger she had a little square tail. She seems rather large, but the others in our backyard flock are a bantam and an itty, bitty week old Ameraucana. Thanks in advance for any help! I love how much information I receive here!
