Poor Diamond. She's been getting the feathers pecked off the bottom of her neck like crazy. She's lowest on the pecking order. Well, the other day she suddenly had them pecked all the way up the side of her head and the top of her head! No blood though, thank goodness. I have no idea what happened. I can only guess that maybe she and Pearl were in the two nest boxes and Opal or Jade wanted to use one. Of course they wouldn't bother Pearl, she's top chicken. Maybe she got trapped in the nest box by one or both and couldn't escape? I have no idea. I put some no-peck stuff on her head and it hasn't gotten any worse in the past couple days. I let them out in the yard almost every day, unless there's a hawk around when I go out or it's raining. I've been giving them some extra protein just in case too.
I was looking at pictures of gnat bites and to me it resembles pecking. Just cover all bases. The gnats are really bad and killing off lots of birds this year. I think this is what happened with my Rain. When they go in the coop at night I speay cintrella on the coop, must the window areas and mist the run. I also put lemon grass in the nesting boxes.
You can also put blue kote on her. It will stop them from pecking and give her time to heal. Make sure it doesn't get in her eyes.
Mine have started laying on the floor of the coop in the corner. That's probably because the younger ones have been sleeping in the nest boxes and the olders probably don't like it. Tonite I had to move Precious off the eggs and rake them out, she was not happy with me. I've caught 2 of the ducks trying to sit too, they are not as serious as Precious appears to be.
