Our flock of 4, 2 RIR (or Production Red), 1 BO, and 1 Australorp are getting close to 16 weeks old, and just yesterday, I heard an alarming sounds almost like a cocka.... it was quite short but pretty loud, and I think it was from Heaven, the Australorp. Though I am also worried about Red, with her new tail feathers seems to be turning downwards...(last picture, front left). so now I start to worry again if we have any roos... Here are the current pictures of them - please let me know what you think. Thanks!
