Thank you everyone. I guess it boils down to thinking I am doing right and being shocked a bit when I lose one. Have not done necropsy on any except "grandma". I had to know with her. She was the one that was eggbound. At least when they have died on me it has been pretty quick not taking days on end. I will be looking at sending a bird in if I lose another. No signs of illness in the flock at all. Normal then BOOM gone.
I would understand it more if it were the older birds.
OK so today is a new day. Going to be warm and melty so that should be fun.
Planning the greenhouse and deciding to go with more of a standard structure. I found automatic opening windows for ventilation. Pricey but would be worth it to put a couple in rather then lose a lot of hard work.
Since we are not moving anytime soon (like ever) I am looking at using the twin wall panels for the greenhouse.
Breaking out the graph paper as spring is coming before we know it.
Have a good day everyone and enjoy that sunshine!
