Next spring seems a long way off but I like to make plans in advance. I currently have 8 blue Orpingtons with 1 blue orp rooster in the mix. Come spring I will be acquiring Belgian Cuckoo Malines eggs in which to hatch. I am sure I will get another rooster or 2 in that bunch. I don't want the roosters and hens to get mixed together when I plan to breed both strains seperately. I'm not sure but I think a lot of people keep their roosters in with their hens right up until they decide to breed them. They can be very protective of predators and this may be one of many reasons. I currently have an 8 x 16ft. coop with an 8 x 16ft. open air florida room attached to the front of the coop for them to stay in surounded by a 33 x 52 ft. fenced run area. I sheltered 25 birds comfortably in there the last few seasons. I've had 3 roosters and a few broody hens and I know that roosters like all the girls! The hens of both breeds will be okay together mostly but the roosters need to be seperated from them when we decide to reproduce their specific breed strain. I will then put hens of choice in with the rooster to fertilize the eggs. At least I think this is how it is done? I did a heck of a job on building our coop and run area but have no clue what goes into setting up a breeding pen persay. I have to assume the rooster will be living, eating and sleeping in there full time and more or less quarantined during the selective breeding time. Do you keep the hen right in there with him or what? Do you need a nesting box? How much space for a rooster and maybe 3 hens or more of his kind. If there is a u-tube video that would help me I will look for it. All comments and help appreciated!
