I ordered day old chickens and ducks from a hatchery. 5 Buff Orps, 5 Silver laced and what was suppose to be 2 Khaki Campbell ducks and 2 cayuga ducks. None of the ducks are what I ordered but my issue is, I raised them in the brooder all together then took them to the coop for 3 weeks so that they would become used to sleeping/nesting in the coop. When I started letting them out during the day, I started with an hour and then worked my way up over several weeks to free ranging all day. But every night I would exhaust myself trying to gather them up and put them in the coop. They would come back to the pen at dusk but they would never go into the coop on their own. I tried every suggestion on coop training that I had read. The chickens would pile up on the ducks in the middle of the pen/run. I assume for the body heat. Now my chickens sleep on the ground with the ducks no matter what I do. I put little perches in the run for them and they do get on them but not at night. The chickens even stay in the creek all day foraging for bugs with the ducks. Ive never seen chickens that act this way. I tried to separate them several times but it was a disaster. So long story short, will my chickens "grow into" wanting to go into the coop to nest and sleep? They are only 8 weeks old now and I worry since winter is coming that they will freeze if they continue to sleep with the ducks. I also want to have a predictable nesting area so I know where to collect my eggs.
