I have two four week old muscovy ducklings. I have put them up in a brooder cage that is built into the coop and mid afternoon saw the two of them outside in the yard free ranging with the flock!? I captured them and put them back in a separate brooder room and closed the door....before long...there they were in the main coop sitting on the floor and the door to their room was still closed!? I am going to name them Hoo & Deenie! How ever do you keep them up at night to keep yours safe? I find that these two just return to the main coop at night with the flock and they are just babies. They are afraid of me right now and haven't decided it was time for treats since the flock would bowl them over to reach any treats thrown to them. I would prefer they stay in with my pilgrim geese at night but so far the geese won't have them close so I am letting the ducklings return to the coop at night. I know that they can't stay in there as ducks always make quite a mess. Any suggestions from duck owners?
