i just built a new loft and i want to transfer my pigeons into them. the problem is they are sitting on eggs. how can i do so without disturbing them too much? i suppose i can open the cages in the loft but i am worried they may not want to sit on the eggs with their new found freedom. how about the nest - can i move them to a new location? what about just the eggs? or would it be better to wait till after they hatch? i'm tight in space so the sooner i can get these rabbit cages out of the way, the better.
