My BC Marans have not learned to use the roost. They are 18 weeks old. I blocked off nestboxes and they just kept huddling on the floor. So i thought to my self, time for plan B. Went out at dark to close coop up and lifted each one up to the roost. Night 2, all on floor again. Repeat lifting them to roost. This goes on for the same way for 4 nights. Most of my other breeds either learned to roost on their own or only needed help one or two nights. So my patience is starting to wear a little thin. Night 5, I go out and 2 birds are on the roost. Lift rest up. Night 6, go out and 4 birds are on the roost. Lift rest up. ( Thinking to myself, they are finally getting this) Night 7, go out and ALL , yes I did say ALL of them are on roost. Whew! Let's see what tonight brings.
