With every pigeon that i've had/ seen, their droppings turn a light brown right around the time to lay eggs and so on until they're done. Is this normal or are my pigeons just weird. thanks. let me know. this would help greatly.
I usually notice the big "bombs" when they have already laid and come off the nest after several hours. The first thing they do is leave a deposit that looks like there was no way it was left by a pigeon...more like an elephant!
