We have a barred rock hen who has been unable to stand or walk much for nearly 2 weeks. We first noticed it 2 Saturday's ago. I did a ton of research and found that it is probably rickets. She squats down all of the time and seems to rest on her "elbows" or whatever you'd like to call them. Once we figured out what we thought it was we started her immediately on Poly-Vi-Sol and the rickets diet 1/2 egg white, honey, oatmeal and yogurt fed divided 3 times daily. At first she improved some to actually being able to stand and walk some. Now she's just plateaued.. She's not making any more progress and probably hasn't in about a week. She can't go more than a few feet without getting tired and having to squat back down. She's still eating like crazy and tries to make her way around, though. We put her in a cage on the roost at night and only let her out for some time during the day for fear she'll hurt herself more or get picked on too much. She gets into a nesting box to lay, but it takes her quite a bit of work. We have a log in front of some of the boxes for her to make it easier, but she doesn't always use it. Today I felt her toenails as some said with rickets they'd be soft, but they're not. I don't know if they were in the beginning or not. I can't find any information on how long it may take to get her better, or when we should see what type of improvement, or what else we can do... Any help any of you can provide would be wonderful. I am feeling very badly because we have 5 barred rocks and for probably several weeks now, we have had one that just wouldn't get up on the roost at night. I assumed maybe she was just too big and couldn't get herself up there (however, she's really not that big. No bigger than her sisters...) or that she just plain didn't want to. She would often roost on the edge of the nesting boxes so I thought maybe that's just where she liked to sleep. Every night I'd put her up there... I'm hoping that by doing that I haven't caused some irreparable damage. Now looking back, I'm sure it was her and it was warning signs of something we just didn't know was coming. We are brand new to chickens this spring..
