They will eat baked sweet potato and pumpkin but theres never really a lot of these leftover (my fav).
So I had a crack at a carrot cake and liked the way it turned out , birds like it too

Just a madiera cake mix ( will br trying a butter cake mix next time ) , 4 carrots , 4 eggs ( no shells this time ) and milk (could use apple sauce if your worried about lactose ) ..
All done in the food processor , comes out a heavyish , orange slab of sorts ...very cheap and easy and hopefully packed with vitamins ...just sharing .
