See, I thought they just had resistance, not immunity. I need to read again.
These pullets haven't had pox before. They're the babies of my birds that were sick last year. My hens and roo seem to be fine.
Trying something different here. Instead of moving the 7 feathered-out chicks to the grow-out pen, we moved the brooder & chicks to the big coop, where they are on four cement blocks. I figure by the time they outgrow the brooder, they will be accepted by the four grown hens & more easily integrated into the flock. So far it's working well, everybody peeks through the brooder at each other but no overt displays of hostility by the hens. They can't get through the hardware cloth the brooder is made out of. I hope this works - it would be nice to cut out the extra step of putting them side by side & also having to let the young ones grow until 6 months or so. I read here on BYC that this works so figured why not try it & see - I can always move them back to the grow out pen if necessary.
