I still haven't quite finished my coop, but I did manage to finish my tractor a couple weeks ago. We were ready to move the 4 to 6 week old chicks out of the house due to all the dust, but the wire dog crate wasn't ideal for warmth in the garage. The chicken tractor was originally a beat up old rabbit hutch I got for free off of craigslist. I add the lower wired frames, and added 2X2s around the bottom for stability. I put on tires from an old discarded BBQ that are removable. I replaced the hardware cloth on the floor of the second level to accommodate the opening for the ladder. My 8 year old made the ladder/ ramp out of scrap from the coop project and large craft/ popsicle sticks. Then we primed and painted it a pretty shade of blue exterior paint from Habitat for Humanity Restore in Garden Grove @$3.00 a gallon. It currently has a brooder lamp attached to it because it goes back into the garage each night for the chicks to stay warm since the outside temps at night here are still in the upper 40s. When the hens are full size, I figure it will hold two at a time, or it will be an isolation area when needed. https://www.backyardchickens.com/forum/uploads/20741_100_1866.jpg https://www.backyardchickens.com/forum/uploads/20741_100_1874.jpg https://www.backyardchickens.com/forum/uploads/20741_100_1897.jpg Here is how far I am on the coop: https://www.backyardchickens.com/forum/uploads/20741_100_1763.jpg My total cost were about $10.00 turn it from bunny rabbit hutch to chicken tractor/ temporary coop. The only supplies that were purchased were paint and hardware and hardware cloth (but it is being used and calculated in the coop project.) The weather has been pleasant lately here in SoCal. It was in the low 80's yesterday and the chicks loved being out in the warm sun. They all roost on the broom handle perch in the evening when the tractor goes back into the garage. I edited because I didn't manage to add the pics before hitting the return key. Oops.
