firstly let me thank you for your replys some constructive and some otherwise
i do not race pigeons and do not kill them, if they are not too good at racing.
neither would i breed young for the specific purpose of racing the parents home to feed it, then kill it once it has done its job.
i know that not all people that race do this....just most.
i have four pigeons that i rescued from being killed by developers and as they were very young. spent 6 weeks or more feeding before putting them in a loft in my garden.
i did race pigeons briefly 25 years ago.
the pigeon that is not well has a respiratory pathogen. and rattles when it breathes
at first when i noticed it it was not too well, i seperated it from the others and noticed it had white down its throat. i took this as canker and treated with spartrix. the pigeon perked up but the breathing was still rattled. not wishing to spend money at vets.because sadly all you get is a big bill
i read on the net symptoms and causes and through self diagnosis etc i thought it sounded like chlymidiosis. this is a form of chlymidia that causes respiratory problems...henceforth i was told doxicycline was what i needed to administer. SO all you bird lovers what i was hoping for was some good advice from others that know far more than me.........and asking the wife cant do much good! ive never known a woman who knows how to do anything other than spend money.....vic
