I have 11 pigeons... 6 females and 5 males. All the females have paired up together and lay 4 eggs in each nest. One pair of males has paired up together.. with no eggs. The other 3 males spend most of the time fighting each other and trying to get the attention of the females. I thought if I left them to it they will sort themselves out eventually, but now is been 6 months. I tried to put a male and female in a large dog crate... but they just fight like mad and I am worried they will injure themselves. One pair seemed to get along.. but when I let them out after one month in the dog crate.. they just went back to their old mates. What can I do? I want my birds to actually reproduce!!!!!
