Okay, so my fiancee went to a fur and feather swap today and came home with four silkies(we thought two of them were hens but now think they might all be roosters, unless hens can crow?) He also came home with six pigeons and four morning doves. (Oh and three japanese bantams.) I don't know a thing about pigeons or doves. Any ideas or tips on how to care for them or make them hand friendly?
