i think your answer is in your own observation .others birds feel lighter than yours yet "blown up" at basketing. i wouldnt cut your feeding down , yet look to change it . what do feed and when , what quantities etc ? and be-friend the Polish man , he is more likely to tell you things than the other local boys .
i used "High Flyers" after 2 reccomendations . maybe too late for next week tho ?? they like to know a week in advance , good luck pal. http://forum.pigeonbasics.com/topic/86713-struggling-to-find-a-courier/page__p__1042536__fromsearch__1entry1042536
