Racing Pigeon Nesting
I have experimented over the years with different types of nesting material and I have finally settled on simple twigs which can be purchased from local pigeon racing suppliers.
I like to put the twigs in a clean area in the loft or outside as long as it's dry, and to let the birds collect their own and build their own nests. This way the birds make a full contribution and feel happier that they have built their nest in their way.
Some people simply place the twigs into the nest bowl but I don't think the birds are entirely happy unless they have worked and achieved the results they want. If you don't buy the twigs and put them in the loft, you will find that the Pigeons Loft.
Don't clean the nest bowls until the young have been weaned because the build up of twigs and droppings makes for excellent insulation providing warmth and comfort for the young squabs.
