Went by my moms tonight and she insisted i take home one of the pullets her friend gave her. I ended up taking both since they're "sisters" and mom doesn't like them anyway. They were both underweight from not getting fed, one has a crossed beak(i have been trimming to help). and the other was perfectly fine until a few days ago. The end of her middle toe looked like it had been smashed, i thought maybe someone(one of the bigger pullets) knocked a piece of firewood on her toe when they were out running around. it looked flat on the underside of the toe and was purple-ish. WELL, tonight when i checked her out her toe looks AWFUL. It's totally shriveled up around the bone and brown, almost half way up the to then it just Stops and turns back into healthy-looking fleshy toe. It literally looks like the tip of her toe just died off. what can i/should i do for this? She seems OK otherwise, interested in the water and was headed for the food when i left them. I have them isolated(together) in a brooder area. They're approximately 3-4 months old bantam EE mixed girls eating "all flock" feed. bug/worm free too still underweight but gaining it back.
