I have concerns about my Australorp chickens. They're 30 weeks old and still haven't laid eggs yet. I'm wondering if I have roosters? Do Australorps crow like other roosters? And yess i' new to chickens, this breed anyway. I also wonder if my dogs barking are too much for them. They've been aound them for 10 weeks now. Who knows what going on but with 2 dogs 2 cats kids someone aound here needs to earn their feed bill besides me. Hahaha Any suggestions would be great.
