Unfortunately the white bird is a Cornish Cross - at the point that he/she is at now you are beyond the point where careful management *might* prolong it's life beyond the point of usual processing. If you are not prepared for or don't wish to deal with processing I would suggest finding someone who does want a nice meat bird and then you can work on finding yourself the layer you wanted. So sorry.
Your other two are beautiful girls! Just noticed your location - I grew up making trips to Wenatchee at least once a year to visit my aunt and uncle, BEAUTIFUL area!
