DH and I are mostly done with building our chicken tractor. It will be finished first thing this spring, as soon as the snow melts. That sucker is HEAVY!! Good thing i have the little tractor for moving it.
I plan to use it mainly for meat birds - I like the Cornish Cross for its ample supply of white meat. It may take a little trial and error to get a good system set-up to do this efficiently and end up with a good product. The 2 batches of cornish that I raised so far have only been in the barn, but they were always busy scratching in the bedding looking for treats (BOSS and Cracked corn) so I think they will do OK outside with moving the tractor every day or so.
DH has a couple of friends that would like to raise chicken but do not have the space or legal right to do so (city dwellers). DH has proposed that after we have our first batch of Cornish-X raised and butchered, we do another batch to split with a friend form college. That would be great - he was a farm boy and would love to come help butcher in exchange for meat. But, DH has also talked with a friend from work about raising chickens for him. That would be a "you pay for the feed and you help butcher - then you get your share of the chickens" agreement. Not sure how that will go as I will need to determine how much I would take out of the batch for my effort of taking care of them every day for 2 months or so. At least this friend is a large game hunter, so even though he doesn't know how to butcher a chicken, he wants to learn so he can start duck and goose hunting, lol. Willing help is a good thing.
3 batches of Cornish-X will be a lot for one summer - maybe too much - But only time will tell.
