Hi I am having an issue integrating my 6 hens and 1 rooster with my older flock. The littles are 14 weeks. The older ones range from 4 years to 7 months. They all free range fine no real problems. I put them together at night but when I check on them in the morning the littles will not go out in the run. They stay in the coop where there is no food or water. Do I just leave them and let them adjust? I don’t want them to get dehydrated. Help.
