I've read it the opposite way, GC roo covering WL hens (I have a pen of them set up now). Take any daughters back to their father.
So far I only hatched out two a couple of months ago and I lost those two chicks. I hadn't gotten around to trying to set any more until recently I've collected a few eggs. I hate to raise too many chicks in the middle of winter. I also have a couple of two week trips coming up and my house sitter (my son) gets overwhelmed if I have too many separate pens to care for.
It's bad enough that I leave him with MANY hundreds of birds, alpaca, sheep, dogs, finches and the llama.
