Also like with old dressers or other wood furniture can be re-purposed to build something new. Just need some power tools to do it.
Used furniture that is solid enough to be of any use is probably too valuable to be converted to a chicken coop -- as well as too small -- and might better be sold for the money to purchase materials.
Unwanted doghouses and outgrown children's playhouses have far more potential.
It's important, even when trying to build something inexpensively, that chickens have certain space needs, that is, for each adult, standard-sized hen you need:
4 square feet in the coop,
10 square feet in the run,
1 linear foot of roost,
And 1 square foot of permanent, 24/7/365 ventilation, preferably located over the birds' heads when they're sitting on the roost.
So a flock of 4 requires a coop no smaller than 4x4 with 4 square feet of ventilation and a run no smaller than 5x8.
A flock of 6 requires a coop no smaller than 4x 6 with 6 square feet of ventilation and a run no smaller than 8x8.
A flock of 10 requires a coop no smaller than 6x7 with 10 square feet of ventilation and a run no smaller than 10x10.
Additionally, though chickens do not stack for storage and thus height can't compensate for floor space, the coop has to be tall enough to make that ventilation possible.
My
Little Monitor Coop is designed to meet all the minimums for a flock of 4. It's not a cheap build, but it does illustrate what's needed space-wise to make for a long-term, healthy environment.
