nice to have all the birds like soldiers but maybe these birds wanting to nest elsewhere shows a bit of character,one of my yearling cocks would not take a telling and after trying to move him my dad and me let him nest on the floor,last week in june he won 2nd federation open dorchester 370mls and 1 week later scored appledore 400mls,nearly 800mls in a week for this yearling cock,the following year the cock flew to a different loft and was less than average,at 3 yr old he was back in the old loft nesting on the floor first week in july 1st region nantes 614mls on the shift,so imo let the birds be happy. ;)
