It does the job! I used it for 18 Baby Chicks that are now outgrowing it. I would say suitable for 30+ New born chicks, 15 4 month olds or 10 Full grown chickens. 
It is sturdy, you will definitely want to stake it in the ground, otherwise it will blow away and have gaps at the bottom. With an electric fence this is perfect for spring summer and fall. Could technically be winterized if dug into the earth and tarped off.
