i have owned  this pair of greys for just over a year , they were proven with previous owner but not with me , they do feed each other . the hen is 2008 closed rung with cites, she was already plucked on the chest when i purchased them but it is growing back( she says hello and is friendly , the cock is plucked bald on his chest and has a sexing ring ( he is a growler) but due to the inaccuracy of his cites i am giving him away free with the hen .
