Running ahead of avian flu

I culled 8 out off my 11 hens today. I'm not sad about it, after they stop laying I usually cull and make stock out of them. I would have done this cull soonish, when it's not so cold, but avian flu is all around me. Reports coming in across MA and in the town next to me has 2 cases already. It's not possible to secure my run right now, and little birds run in and out all the time. I have left my bad ass rooster, Buster, and 3 hens to keep him company. I hope he makes it, he killed a hawk to protect his ladies once. Only 2 even had any proto eggs in them, they were over 2 years old and I was only getting 1 egg a day, it was time. Culling now, tho, means I can use them for food. If they got flu they would have to be cleaned out and somehow dealt with safely. Now I have 30# of hen in the freezer to use later.
