I am trying to learn how to make my own coop because I am looking after my birds with someone else's flock and I intend to move away from this property, probably within the next year. I'm considering making enough housing for 8 birds and separating the flock into 2 groups for spring (separating the roosters). I figure I can make another 8 bird (or larger?) house once I know more, if we want to get more birds.
These are free-ranging, the weather can be wet and the ground gets a bit boggy. The temperature gets up to 35°C(95°F) in summer and down to -2°C(28°F) over-night in winter. There is an orchard here and low lying shrubs under which the birds shelter from weather and hawks. The only predators we get are hawks and pet cats (who are only a worry to chicks). Possums (NZ brush tailed) might have an interest in eggs but seem to have paid no attention whatsoever to the birds so far, and the have often been left for weeks without anyone locking them in at nights.
Currently we have about 20 birds roosting in a shed approx 3mx2m(6½feet x 10feet) The sun facing end of the shed is open to the elements, with chicken-wire covering it. There is a dirt floor covered in barley straw, 2 roosting poles running the length of each side of the shed and a unit of 3 nest boxes at the far end of the shed from the open end.
We have a small tractor we use as a brood hutch to keep predators off the chicks.
A couple of questions:
Why do people suggest raising nest boxes? Do I need to consider having a raised floor?
