Hi am getting ready to build our new chicken barn but need some advice before doing so on flock numbers... we are wondering what a good Hen/Roo ratio is? I only plan to keep 1 Roo per pen but am not sure how many Hens would be an appropriate number. We have a few different breeds and are kept seperate (my mom's a chicken nut) so I will list them seperatly below. Silkies = 1 Roo to ? Hens Bantam Cochins = 1 Roo to 5 hens (I was told by a friend who raises them is that correct or way to many?) Seramas = 1 Roo to 3 hens? or would 2 be preferred? I have been told both Standard Rumpless Arauchana = 1 Roo and 5 hens is what we currently have is this ok or should we downsize a little bit? We are planning on building a 20x20 with indoor and outdoor areas completly enclosed in both areas so not sure that room will be an issue I just want to make sure we get good coverage for fertile eggs and so our chickens remain healthy and happy and not overly bothered by the Roo. Thanks in advance!
