My young Rosecomb's leg fell between the Eglu Go lousy slippery roost bars and she is limping w a swollen knee that sometimes is held out in front of her or seems to bend in under her sometimes. She's preening, and I want to be sure I am doing the best I can. Tiny bits of baby aspirin, arnica, b12 and all the food she wants. She can roost at night, walk but w only tiny weight on it. Pain yes bc she closes her eyes when I examine her. No obvious injury but swollen joint at knee. Eating a lot, drinking. Could she walk if broken/dislocated? What are specific things to look for to determine break, dislocation etc? I see nothing but swelling.
