One of my hens was sliced pretty deep by the roos spur. I brought her in and cleaned it up. I then examined it and it didn't appear that anything other than the outer layer of skin was sliced. I sewed her up but she is limping pretty bad. The injury happened on Saturday and it is now Wednesday. Any input please? Thanks. I don't have the money for the vet. Just to walk in the door is $55 and I am flat busted broke.
