So that is the question. We we bought 3 runners at an auction 1 was a drake and the other two are female. We have seen the drake mounting the girls but at what age will the girls start to lay eggs? After three weeks of feeding peas as treats they now they will get to with in bout 5 feet of us. Just waiting to see when they will start to lay eggs. they spend a lot of time swimming around from what we have seen. The previous owner didn't seem to give them much chance to swim. Now they have a good swiming hole to play in.
