Tonight is our first night with our chickens - 4-month old pullets. There are seven of them. When it started getting dark, two of them, walked up the ladder from the run to the coop and then blocked the entrance to the coop - the others couldn't get in - although they tried for awhile. We finally opened one of the small side doors in the coop and managed to shoo the two that were blocking the entrance into the coop and onto the roosts. However, the rest of them are still roosting on the ladder. Will they eventually work it out so they all go into the coop and onto the actual roosts? Our coop is built in such a way, we can't reach the ones on the ladder - so we can't move them ourselves. Any suggestions? Thanks.
