I asked a whil eback about swollen crops. Everyone was agreed that they were just overeating. Ok. No wtheir crops are swollen every night. They are all better in the morning but by the end of the day they are swollen again???? They have grit. I make sure that they have feed at all times but I only see them really eating it in the morning. THey like to pick at their grass and my veggies the rest of the day. I only feed treats in the morning. By treats I mean a few slices of bread and some fruit. Is this normal??
