my chickens are fouth months old and i have had them for two months now and they don't roost all four of them just huddle in a corner on the floor in the run and in the coop and i have a few roosts outside and one long roost in the coop big enough for all of them to sit but they still huddle in the corner. i go in sometimes and pick them up and put them on the roosts during the day and right when i put them to bed i try. they will sit on it for a little while and then just hop off. they also dont know how to get in the nesting boxes and none of them are to high off the ground that they cant get in or on. What should i do because i am expecting eggs in two months and i dont want the egss all over the floor?
