Yeh I think the stack of tires is a great idea if you are out in the country. When we move permanently I want to try it. Right now I usually do five 5 gallon buckets with baby reds and some Yukon gold. Here you canto a spring and a fall crop. So far this year we have not even had a hard freeze. 2 of our chickens molted again about 6 weeks ago. Crazy weather this year.
It’s warmer than usual by us, too! It’s been in the high 40’s and low-to-mid 50’s all week - with no end in sight! I’ll take it! It makes the Winter shorter, but I DO like snow for Christmas. :)
