Had a ton of work to do when I got home so I didn't have time to take pictures of them. I'll go back out tomorrow. Poop is a tad runny, but still sits in a solid mass. No worms, but not sure what I should be looking for.
The larger of the two chickens seems to be making an improvement, but it's tough to decide.
When I bring them in and set them in a box to feed and force vitamin B into them, they just sit there. They don't make an effort to get up and move around the box. As a test I brought another chicken in to see what they would do and they tried to get out of the box right away.
However, when I go outside, the one chicken that I think is doing better does seem to be up and walking around. Within the next day or so, their run will be fully enclosed and I can put them outside (supposed to get snow though) to see how they do.
