First of all I don't know if this is the right place for this question but if it's not, I ask moderators to move the thread to the right section
So, I have a 3-years-old Australorp rooster, Isa browns and other Australorp hens. Now, my Isas have a lack of feathers on the back. I'm pretty sure that it's not a problem of lice but it's the rooster. He's not aggressive but maybe he's too big for Isas, I think he's 4/4 kilos and a half. I should trim his nails and spurs or it's just a problem of difference of size? I thought a dual purpose roo was not so heavy for a normal size breed, thanks.
