I am thinking of having two separate pens for breeding besides my main pen. I have customers that do not want to buy fertile eggs, so I have our hens for egg consumption in one pen and wanted a separate pen for breeding. We have decided for now to only breed two different breeds. What I was thinking is having 1 rooster with 2 hens in each pen of each particular breed. Would it be a bad idea to keep this as a permanent thing? The same two hens permanently with the same rooster? Would it be too much for the hens to have this rooster constantly with them or will they be OK?
