Ahh, didn't realize you had chicks in there.
So about 5x6', that is going to be very tight space for 15 full grown birds come the middle of winter. Not sure you can even fit enough roost length in there let alone anything else.
Might want to plan on expanded run with solid cover and wind blocked sides.
Crowded Cabin Fever is not a pretty thing.
Might I suggest for future chicks?:
