Hey i have3 hens and 4 days ago i noticed ones foot was swollen and she was limping. She doesnt have a scab like the pics i have seen of the bubble foot.i got some oxytetracyline and have been giving it to her but now i noticed roubdworms in her poop. Any ideas of what can be going on and how these things should be treated? And should i treat the other 2 hens as well???
