I have a male pigen and female dove that mate. I had seen him mount her frequently but I blew it off as unusual behavior that was probably derived from the fact that they grew up in a small cage together (these birds were given to us about a year ago because we have an outdoor aviary and the old owners were moving). But they are reproducing. I did not think it was possible, but it is. I have been doing some research and it seems that Doves have 78 chromosomes and Pigeons have 80. Some articles suggest that they are both subspecies but I am not sure how this can be if they have a diffent number of chomosomes (if that is the case, why are humans and chimps not simply a subspecies). The problem I have is that the baby never lives more than a week. Information on this site suggested that both Pigeon parents care for the baby. But I have never seen either parent feed the baby. I also came across something on this site called Pigeon milk. Should the dad be able to feed the baby with this? Is this instictinve or could he have simply never learned how to do this? This is the second baby they have had and they both looked healthy then just up and died within a week of hatching. What can I do to help the next baby live? Can I milk the dad and feed the baby myself. What else would a pigeon-dove hybrid baby eat? Any advice would be appreciated.
