If you also use this type of nest this tip can serve you.
Last year, a male regularly messed up the materials of his nest or the abductees. In order to certainly start another brood.
The bottom of these nests being flat, the eggs were scattered and therefore a risk of not being brooded was very possible.
So I looked for a solution to avoid this inconvenience. By trying several type of concave nest bottom, among others those in rope and coir, incorporating them into the plastic nest. This male continued despite all to want to remove these funds !
