I have 3 hens (all of them 2 years old) and one of the hens I noticed started limping for more than a day now. I'm especially concerned because we had lost our 4th hen about a month-ish ago, and that hen started off limping as well. The currently limping hen has always been healthy, and never been around the hen that was starting to die. Oddly, she never lays any eggs, but we've never seen any signs of her health degrading. On top of that, I'd like to know what happened to the 4th hen.. I never knew what had happened to her. As stated, she started off limping and that happened for about 2 weeks. I didn't see any signs of bumble foot. She only laid one tiny egg in the span of her sickness and never laid again. We gave her baths, cleaned her up and gave her her own space to live (separated her after she got bullied and pecked at a lot. at one point her head was bleeding). But, it didn't seem to effect her condition. In that time span, I believe she lost her eye sight. She didn't know where she would walk, and didn't know where to peck at to eat her food unless she was pointed into the right direction. I also noticed that she had erratic head movements from time to time. It was like a girl giving me sass with that neck movement... except this involved violent up-down-side-side and circle like twirls. Then after a full month, her health plummeted, she stood in one spot all day... white insects (perhaps lice) and tiny ticks grew on her. In her last week, her head movements became body spasms. At that point we didn't know what else we could do. So we hid her from the other three. I live in the suburbs, my neighbours think I'm crazy. We made the shed their home, and half of the backyard as their place to roam. They've all been healthy and never had any signs of health degradation until the recent death of the 4th hen. I would like to know what happened to the 4th hen, and if anyone has any idea why my hen is currently limping? thanks in advance.
