After so many years of raising pigeons, there are actually many problems that fanciers have not encountered. When we first encountered it, we also thought that some problems might be coincidental. But some of the problems are really not a coincidence. Some pigeons should be culled.
First, some pigeons actually lay eggs normally, and they hatch normally. But the pigeon will die in a short period of time, and some will start to lose weight inexplicably when they develop to about half a month. It's the same even if you change your mate, and there's no problem with raising. Then such pigeons have some problems with genetic inheritance and need to be eliminated.
Second, some pigeons are normal for you, so you may not know why after a month. At this time, it may be brooding, and the young pigeons are also following the water poop. Such pigeons have stubborn stool and are repeated for a long time after the intervention, so they are eliminated.
Thirdly, the pigeon that is paired with this one pigeon is relatively thin and slower, and the development is relatively slow. Sometimes it's good to change a mate, that's fine, but some pigeons are the same for other mates, so you have to pay attention to the culling.
