all of my flock are gaping/panting at night. It is hot and muggy, and definitely heat related here. maybe 80 in the coop. The ee's especially seem vulnerable to the heat.
I have two hens gurgling with their breathing. THey are both between 5-6 years old, so I am doubtful it is mareks, even though they have been exposed, obviously. Don't know if it is the weather - it has been hazy with smoke from canadian wildfires for days now.
I think everyone is holding their own for now. I think it has been about two months since I've had to cull anyone for mareks. I have some two year olds that seem mighty skinny, but have almost softball sized crops at night, so they are surely eating.
its been the worst spring for broodies, there has been a broody hen or two in lockup for almost 3 months straight now. The sad thing is that with mareks in my flock, I can't let them hatch unless I have room for the chicks to be added to the flock, since I can't sell or give away the babies.
