I just went through the same thing, Australorps rooster ,we bought some eggs from a breeder for the incubator and thought to add a couple of these too as long as we had the bator running... we were going to do the australorps a little later on but figured as long as bator is running might as well throw a couple in....We gave gave the rooster 2 hens, turns out he prefers one of them. It showed up in the incubator...The best hen and one I saved the most eggs from - 5 total .....while I was at it, grabbed 2 from the other hen, out of the 5 from the best hen, 4 were clear, one filling up with baby on day 12 candleing, out of the 2 from the other hen, both were perfect 12 day formed babies. He seems to pay most attention to the spare hen, So Im going to remove her . I gave him 2 so he wouldnt be too hard on the best hen , would like to show her in august. Hes very big gentleman to both and neither have much if any rooster wear. He doesnt have much of a spur either just a nubs for a 2 year old. Some of the other breeds we had in the past had dagger , very long sharp spurs. dont know why australorps dont have that. His spuirs cant be 3/4th in long and very dull ended. He can still give you a good punch with them thou. Hes always finding and givng presents to his girls.And Hes not above giving me a good punch if I get too close as roosters will.,
