We raised a few hundred cornish cross this year and would like to work up as we build our market. The limit in my province without purchasing quota is 2000 broilers per year, so that would be the limit for the foreseeable future. The majority will be raised using a pastured poultry system while the weather permits, and we would like to work towards a system where we mix all our own feed, and use medication only when necessary (i.e. avoid the medicated chick starter and the antibiotic/vitamin combo in the drinking water). We want to find which conditions allow us to raise the birds for the least money. I'm building a coop which will hold 60 birds at 8 weeks maturity, separated into 4 contained levels so that I can experiment to find the effects of different changes to the system. I've ordered 60 cornish cross pullets, set to arrive on Friday. The first experiment will use the same conditions on all four levels, first of all to test out the system, and also to confirm that a sample size of 15 birds will be enough to find meaningful results. The conditions I'm using for the first experiment are those found on Anstey Hatchery's website: http://www.ansteyhatchery.ca/after.html . Additionally I'll be adding plain yogurt to the chick starter for the first week as well as offering free choice sand/grit depending on the birds' size. Processing date is 8 weeks after arrival. I'll put up some pics of the coop once I'm finished. I was wondering if someone had any thoughts on the experiment or the instructions on Anstey's website. I'll try to update this thread as the experiment progresses. Thanks in advance for your comments!
