This morning I found one of my pullets with a swollen leg first 2 pics. the last pic. is of one of my pullets that hatched with her so you can compare. They are 5 weeks old, the leg is very hard. She usually stays with the rest of the group but she is just by her self and won't walk very much. My only guess would be green stick leg but I'am not familiar with it any help/how to treat it/what it would be would be wonderful.
