Don’t know..2 years before I packed it all in,I changed Nothing…in my Routine...my youngsters around the loft they ranged and raced around the sky until I got them in.Then I took them to my 1st training spot the same spot I took all my other youngsters over the years 7 miles.. then all went down hill I watched them on release heading south previously they used to circle 2/3 times then flying north. ( I thought oh well ) l lost about 16 out of 30 birds my birds were well bred and wanted for nothing (Fit as a fiddle their flesh was fine no sneezing etc etc,some mates of mine had the same loses some even heavier!! Weird what’s going on

Exactly the same happened a year later I bred around 40 youngsters all fit …1st toss I lost around 24 same again with other Good flyers
There droppings were fine No youngbird sickness etc
That was it I thought what’s the point it broke my heart + quite a few pigeon men had sadly passed on and some members packed it in.
I’m still scratching my head….weather conditions/atmospheric I don’t know I will leave you to it
