Approx 1400 lanarkshire pigeons training from Innerleithen this morning. Unfortunatley a Peregrine falcon turned part of the convoy a few miles up the road.
Pigeons are Racing And Training all over the place so they could pick up ybs at any point on the journey. I hope you let the 5 fanciers know that on a wednesday morning its better to keep there ybs in,by the way the pigeons have been training from there for years.
Bert Braspenning has writen a small piece in the BHW regarding similar problems.He thinks its related to the pigeons being locked up for too long in the winter months? I had two nestmates showing the same symtoms as your pigeons.I put them in the bin thinking it is a weekness in the Family???It is a complex issue as the same problem you are having can be caused by different things with different pigeons.This E Coli bacteria is causing lots of different problems behind the scenes.JMO
