Eggs Cracker

[jack57]

Hi guys can anyone tell me why is my magpie pigeons are breaking their eggs

read your other thread : weak eggs due to lack of calcium or sitting to tight

I think a more common cause for this is fighting in the nest boxes. This could be a rogue cock(s) going into other box(es), or hen(s) not properly settled to their own box going into other box(es). Keep your eyes and ears open for signs of a commotion in the loft, and you'll find out who are the offending birds.
