Jeff,
I start the day with a sparrow (20grams) and 40 grams of pigeon in the evening. My boy is dropping in weight yet still not hungry enough to appreciate jumping to the glove. He comes to the lure well in the room and is more relaxed but still not hungry enough to respond well. Quixote is a sensitive one.
Is your boy outside in this heat? Mine is inside during the heat of the day.
Harry.
