Nine perches is not enough for ten birds better to have fifteen or more. Every time you feed them whistle and shake the feed can. Build an aviary where they can be outside the loft and see around. Keep them in for a week. After a week feed them a half ration in the morning open the aviary late in the day (low or no wind) let them out. When you are ready for them to come in whistle and shake the feed can. Do this daily until they are disappearing for a half hour or more. At this point you can start putting them in the crate and training them, release them from their own garden the first time or two. Take them 3 miles, if they return fine take them 5,10,20.....make sure the are coming good before moving them farther. On these short tosses you may want to loft fly them first, call them in for a few seeds (only a few) then basket them for the tosses. This will take the play out of them and they should come staright home. Good Luck!
