I have a Dove Release business in Ft Lauderdale I raise white doves/ homing pigeons and recently have noticed when I check on the hens sitting on eggs an egg will be missing. Then a day or 2 later the other egg is missing. I look on the floor and all around and there isn't even a sign of the egg shell. The loft is pretty secure with small mesh wire. I thought maybe rats were doing it but I have set traps and bait and haven't seen a rat in months. What is going on?
