My pair of racers have 2 eggs,proably laid in the first full week of this month June/2012. These birds are my only ones I have so far. I have read some posts that there several type of bands. My Racers are from flying stock, & in time I want to build a racing team. I read you cannot fly birds with IPB bands. My hen has that type of band. Why is that? Also do some Racing Clubs sell bands to their members so they can trace the band number to it's owner if the bird is found by someone? Will these clubs accept birds that have bands which were not bought thru the club for a club race?
