So this is my first time raising "pet" hens. My husband is building them their coop. They're (I have 2 hens) now 8 weeks old and will be going into the coop real soon. However I have no clue as to even what the terms roost, etc mean? What my husband and I seen as pictures of coops is what he's building. It has the big open run area for them, then has like a little "house" with a stick going in it for them to "sleep" in I guess.. then has the other enclosed area with the lift up roof and a divider in between for them to lay their eggs when they're older. Does this all sound right? Also can anyone please clarify for me what these different "areas" are called in "chicken" language?? Thanks SO much!!!!
