Welcome to BYC. Glad you decided to join our flock. X2 on Kelsie2290; coop/run kits typically over state the amount of chickens that the coop/run should actually have in it. The recommended minimum is 4 sq. ft. of floor space per bird (more is better) for the coop, and 10 sq. ft. of floor space per bird for the run (again, more is better). Overcrowding can quickly lead to aggression, fights, biting and feather plucking, and even cannibalism. Please feel free to ask any questions you may have. We are here to help in any way we can. Good luck with your chicks.
