Update: I checked their feets, seems like the "wound" from scab (scab wasn't kernel-like, but flat) has healed. I removed bandages, gave them vit. D. The sitting-egg hen is in the coop, just like yesterday and doesn't limp. The limping hen still limps, but she's in the basement still. I'm starting to suspect the joint/bone injury... I cleaned her poops near her food and water and gave her cauliflower leaves I hope she'll start recovering her leg soon. No egg today from limping one.
