Yes, have fed both, used to get G10 from local stockist, but he gets P40 ones now. I prefer the P40 ones even though they are more expensive. The birds eat them readily, due to Aniseed on them, been advised not to give more than 10% added to mixture as they can be fattening. Last year I added some to Hormoform that I gave to the stock birds and was finding that the birds were picking all the pellets out within minutes. Hope this is of some use.
