I just got three silkies from my next doe neighbor as they are moving. They only used a wire pen with no roosting area or nesting boxes. We have given them a nice coop with roost sand box for eggs. One is laying eggs in box, one is using grass and not going to box and none are going to roost at night. They are huddling on the ground. They are all a little over a year old - I am new to chickens so I am learning as I go. Will they learn to use roost and box ? Is there something I can do to help them? Any help will be appreciated.
