I have 7 geese. Three of them are 8 weeks and four of them are 7 weeks but they stay in the age groups and don’t mingle. The three older geese also stop the young geese from entering the coop during the day and herd them around the garden. How do I stop this or encourage them to integrate. They currently sleep in two different separated sections of the coop because I am afraid to leave them alone unsupervised.
