This is my fist year racing pigeons and took my 12 pigeons last night about 4 o clock about 20 miles, they have been coming good up until now. let them out and they flew round a few times then noticed a big BOP in the sky all the pigeon seem to fly towards it and went really high. coudnt believe it, they went out of sight and i didnt get 1 single pigeon back yesterday. i have had 5 back this morning. gutted
