@@CervineSkol If you look at the underside of the pigeon that the person's holding, you'll see that the feathers look awfully disjointed and a bit irritated. Some of them are actually turning red and this could be due to a broken follicle. I'd suggest that this person would at least seek medical assistance in case any of the blood feathers are causing the issue.
This is actually pigeon rape. Must be traumatic for the bird. Don't do that for entertainment. Pigeons are not toys that breed all the time. They can truly love their partners. If there is no love, if there is no will, if the breeding is forced... Then it's rape
