Hello Peggy, and welcome to BYC! Glad you joined.
As has already been mentioned, that coop is WAY too small for 8 birds. I wouldn't house more than 2 in it and only if the run was greatly expanded.
Standard sized (LF) chickens need 3.5-4 sq ft of floor space, 1 linear foot of roost space and at least 12 sq ft (15+ is far better) of run space per bird. The coop should also offer as close as possible to 1 sq ft of permanently open ventilation per bird with the vast majority of that being a minimum of a foot over their heads.
