I have 10 RIR , 1 EE, 5 Sex Links and 2 RIR roosters that are 17 weeks. My roosters have started their boy behavior of attempting to mate with my EE and 2 other hens. They still run for the most part when you try to pet them. The combs and waddles of the hens are still pretty pink more than red, but the roosters are very bright red. Trying to get an idea of when to expect eggs and also now that my roosters are trying to mate, will this cause any harm to my hens since they are not laying yet? 1st time chicken owner and learning as we go!! Thank you in advance!
