For the first time my chickens have made me cry I went out to play with them for a bit and every single one of them have varying amounts of black "goo" all over their faces and wattles. And I'm sorry, I have six pictures of three different birds but my internet access is very bad lately and I cannot get them to upload. I'll keep trying though as I'm very worried about this. -This happened sometime between 2pm and 7:30pm today -I was out for quite awhile tonight and I did not hear one single chicken sneeze or cough or gasp, nothing -I got a bit of slightly warm water and a towel and although I couldn't get it off there was residue on the towel after I tried -There was no smell -It's been very hot the past week and a half or so and today alone was 100 (heat index) -They have water in the chicken run and inside the coop -I gave them some frozen corn and peas and all of them attacked the treat just like normal -When they went into their coop for the night they all stood around eating their feed and I gave them some good night raisins and they all were very eager for that treat as well -I did get my normal 2 eggs this morning/afternoon Besides this black stuff they are acting completely fine but it's very clear this isn't "normal". Thank you to anyone who can offer information and support.
