I am wondering if they're just in molt or if there is something else going on? I examined their poo that was in the box i brougth them home in, but it just looked as though they hadn't been getting fed, was very thin & watery, nothing alarming or strange. I believe they are White Leghorns, possibly "spent hens". Hen #1(front) has a short comb, she looks healthier at first glance but she is a bit underweight. Hen #2(back) has a big, floppy comb, she just looks pathetic. the comb looks terrible, has no tail & is filthy BUT is a good weight. They're eating & drinking good..they were unsure of the waterer to begin with, maybe they didn't have one like it before? they prefer to forrage rather than eat out of the dish of food so I have been sprinkling food on the ground for them to find. I adopted a WLH Pullet a few weeks ago, she was very pale and depressed looking, 3 weeks later and she's started laying me eggs and is perfectly healthy! Hopefully this will be the same kinda story but never hurts to be cautious, right? So what do you guys think? Just molting or maybe something more?
