Portable barn options - additional costs for each

There are multiple questions you need to answer to discern what you need in a portable coop.

How many birds will be housed?

Will the birds be let out (free-ranging) during the day?

-Assuming they will be safe out there.

What is the slope and area you will keep the coop?

Are you okay to lift the light end and drag it or prefer wheels?

Are you concerned with winter cold?

--To aleviate drafts we can enclose the nest box.

Is enclosure and windproofing sufficient for you or do you want to add insulation?

Do you prefer a roof that is red, green or white/grey?

We calculate that a bird will probably lay 4-6 eggs per week depending on breed.

How many eggs do you want to have per week?
The 8 foot tractor, good for 4 birds = about 20 eggs/week
The 10 foot tractor, good for 5 birds = over 2 dozen eggs
The 12 foot tractor, good for 6 birds = 30+ eggs per week

The regular model prices are 8' $200, 10' $230, 12' $250

Are your birds large enough and well feathered to make it through the winter?
Perhaps you want the nest area enclosed.

Fully enclosing the nest area includes closing off the run except for one ground-level opening, extending the roof on one side and adding a window on the other side at ground level.

Closing off the run side is $15
Adding a window to close the entire nest in is $10

Insulation: Not necessarily required, but per your preference.
If you'd like basic insulation for $10, I can add reflective thin insulation on the top.
Also available on the sides and door for $5.
Full insulation requires additional wood to protect the insulation and the cost is $25

Large non-inflatable wheels can be added for $20. The unit is lifted on the light end and moved on the wheels.

A door is on the nest to access the eggs and nest.
Do you require a full-size entry door on the chicken run side?
If you will let your birds out of the coop you may not need this as you can lift it or tip it over to access the inside. All coops 12 feet long include this full door.

Do you have reason to avoid pressure-treated wood (PT)? The current chemicals used in PT wood are safer than previously. See article here: ============================================
