I've got 4 Indian Runner girls. 3 of them are over 1 1/2 and 1 is 6 months old. I've had a couple "fairy eggs" from what I assumed from the youngest girl. But I only get on the average 2 eggs a day. Sometimes they are 2 great big ones and sometimes 1 big and one chicken size. I'm just wondering out of 4 girls who's laying and who's not! I thought about putting food coloring around the vent or is that absolutuly stupid?
