They have a good amount of space, but they were in a brooder before this and maybe stayed there a bit too long. Needed to introduce them to my older ladies and was nervous about them getting picked on, so I probably procrastinated longer than I should :( thanks for the info, I'll put some salve...
I have several pullets who have picked the feathers off their back/tail area. I have assumed it's parasites, and put some DE where they dust bathe... but it's hard to tell if the problem is fixed? I saw one with a little drop of blood, like she'd picked at a feather again, but couldn't figure...
