Seeing yer looking at the house of Aarden doos is it long distance lines you are after? You've maybe missed the boat for this suggestion but a number of your top distance fanciers locally will be racing their best birds to the nest at the minute with the "Classics" coming up in the next four weeks. Many of the eggs under these birds that will go on to score top prizes from these events are surplus to requirements and often thrown out. If you get into contact with someone for next season you could have 2 or 3 pairs down the same time as their main birds and get eggs out of birds which should be in the best condition they'll be in all year. They won't cost an arm and a leg and will be hatched into your own loft enviroment
