I thought on here in someone's post, they said to be sure to have the crop...now here is the foggy part for me.....full at night, or not full at night.... Can anyone respond, as to which is good or bad. Or if any of it is an issue. THe reason I ask, is we had my watermelons as a treat last night, and fed the chickens the skins with the last of the melon. They attacked it, and when they were heading in for the night, their crops were so full. Thought maybe it was not a good thing to have it full when they were heading to the roost for the night??? What about winter? make a difference. Empty or full? Just curious!
