Yeah, it's pretty much a crap shoot you never intend to play. The odds suck and you never know which side you will come out on.Of my flock of 40, I've had to cull 10 I would say. Several more died on their own. I really hope your flock does well. Don't lose hope! I've had friends only lose 1 bird and the rest of their flock is perfectly healthy.
I hate to say it's a club that nobody wants to belong to but there are a lot of flock owners out there who are members.
We are all in this together!
