One chicken not roosting

[AZKaty6]

I have four chickens and just in the past couple weeks one of them won’t go in to roost at night. Instead she comes up on the deck and roosts on the railing. I have to take her down and put her in the hen house every evening - she’d stay on the deck all night if I let her. Also, just tonight I heard a commotion in the house and it sounded like she was pushed off the roost bar. Couple hours later and she’s awake wandering inside the house right now. The remaining three are soundly asleep. It’s odd this came out of nowhere but maybe I need to add another roosting bar? They’re all about 4 months old so I’m thinking they’re just figuring out the pecking order and she’s at the bottom. Anyone have any suggestions?

Might need a lil more info. How big is the coop??? Since the chickens are growing, it may get a little cramped, (if coop is small). Being on the bottom of pecking order, it would be her that gets the boot out the coop.
Post some pix of your coop so that we as viewers/readers can make a judgement call.

How much roost space do you have? Just one roost at this time?

The coop itself is probably 225 square feet and the house is another 16 square feet. I let them out in the back yard to hang every day after work too. One roosting bar 4’ long. I can post pics tomorrow. I think I’m gonna add another bar this week and see how it goes though.
