Mated pairs switching

Well, I have all my birds back out into the lofts together, my garage breeding is over. Anyway, I have some birds that did not like the pairings I did, I guess. They have swithed off on me. I would be willing to bet they know more than I do. One pairing had been done before and swithed back to the originals. One pair had never even seen each other before but as soon as they were in the loft together they were paired and down on eggs. The third is a crazy story, I have a 07 bird from Randal Berkey and brought it into the garage, paired it to a older hen, and nonfertile eggs. After a few rounds of no good ones I thought for sure it was the hen. Well, anouther hen goes in and no good eggs from her either and I knew she was good. So, I put him out in the loft and when I brought my garage birds out he took a liking to a hen from red rose lofts and are down on good eggs. It is just crazy sometimes and I think these pairs will produce a better bird than I did with my pairings.
