It's a very personal thing how people feed their birds so it is important that you believe in what you do as that is half the battle
Regardless of how they feed, most people's returns are in the same ballpark and stay very similar over time despite massive fluctuations in annual feed consumption/wild food/quality of cover plots etc
This gives you a clue as to the relevance of the particular system chosen IMO.
HABITAT is where it's at. Get that right and the feeding method becomes irrelevent.
I do have a few rough guides though:
Get the earliest poults you can. You'll use a little more food but returns will be the same and they'll fly better than any 'insert latest marketing fad strain of pheasant here'.
I personally use at least 1 hopper per 50 poults, if not more as well as occassionally spin feeding all the places I know the birds like to frequent.
I only feed straight wheat until the cover plots ripen when I top weekly feed rides of maize, sunflowers and triticale.
I make sure I feed when the birds aren't. I don't want to see my birds. Tame birds always fly worse!
I feed my drives of course but I also feed the release woods quite hard too- this helps keep birds roosting there a little longer.
I hate straw for pheasants! Grass rides and leaf litter are far better alternatives to feed on if you must. If you want perches, small lengths of post and rail made from left over timber do the same job.
Don't be afraid of boundaries- everybody has them! If it's a good drive- feed it. It won't make a jot of difference as to whether they find next door or not.
Hungry birds are never going to fly their best. By keeping a constant, ample supply of good quality food available, birds will lay down the fat they need to stay well conditioned which helps with spells of bad weather and means they fly high and fast from day one. There are no thin weedy sprinters!!
