How many birds are in here? I'm a little confused if this is 6 younger birds, or 9? Is this meant to be a permanent coop or a grow out?We have a wooden coop for our chickens but they are going to get to big to fit all 9 soon. (6 chickens are only 4 months old) so we wanted to get a bigger one for them since once grown they will be bigger them our mama hens lol
Unless this is very temporary I'd alter the unit entirely to eliminate the metal pan, and convert it so the entire thing functions as the coop instead of coop and mini run. It's simply too small for even 6 younger birds for an extended period of time and lacks ventilation:
To turn it from 2 small "boxes" (tiny coop above tiny run) into 1 bigger "box" you'll want to remove as much of the inside coop wall as possible, plus the floor. Take out the old roosts too.
Nests might be able to stay as is, or may need to be relocated elsewhere or replaced - depends on the structure of the coop and how things inside stack up once done.
Run a new roost(s) lengthwise or widthwise across the newly open space, depending on how much roost is needed. Ideally you’d like 12” per bird but 10” can suffice in many cases.
Board up some of the external wire walls so that the roost area is protected from winds and rain. Do NOT fully cover up all the wire, you need ventilation and natural light, so at the very least a few inches under the roofline should remain open. If your climate allows for it, you can leave entire walls open with just the mesh, or make it convertible for the season by covering up open walls for winter, and then uncovering for summer.
