I am in a similar situation here! 15 Dom chicks arriving from Cackle the end of the month, and I haven't even closed on the property yet! (next week) I have seriously over planned everything but am sure I will still get a "surprise or two"!
I plan on using the MHP ( I think it means Mama Heating Pad) method and raise them indoors for a few weeks until I can get the 6 X 8 coop and massive run(s) built. I have been really reading up on the permaculture theories and I will post pics as I go!
This site and its members are an awesome resource and makes me confident that it will all work out fine!
