I will not be racing my Y/Bs till we are over the 100mile mark. To put 32 Y/Bs into a crate is madness . For the last 2 Y/B seasons the day after the 2nd race I ve went into the Y/B end to find most of my Y/Bs throwing up and that the start of Y/B sickness That my Y/B season over Im not one of these fanciers who think its cured in 2/3 weeks. I think about the welfare of my birds and others I have watched Y/Bs in the crates they get stressed so easy ,some have never been basket trained they dont know how to drink/ The start rubbing against other birds fighting breaks out Im sure ever bird in the loft has its own perch/its own space Im a pigeon lover before being a fancier TO CUT THE STRESS PUT IN LESS
