None have recovered. I'll give them a couple of days as they scoot around the brooder floor on their hocks with the other chicks running over them, literally. After a couple days, they get pretty weak and at that point, I will end their predicament. So, they need to get up on their feet (and I don't see how with a joint that is so very stiff) or die. I refuse to build crutches or little wheeled carts so my birds can get around. I just don't have the patience for it. Also, I breed my birds and they need to be strong and healthy because I've learned that "what you allow in your flock is what you will have." I think that applies to every part of life as well.
Yes, same genetic line from healthy birds.
I feed fermented feed: Purina Flock Raiser mixed 50/50 with Nutrena Gamebird Grower. This gets me a protein level of about 22%. I have two 5 gal buckets going. The morning feed is straight fermented feed. The evening feed is the same with just a little bit of rolled barley and BOSS thrown in for texture and interest.
They almost never get treats. When they do, it's sprouts or something green from the landscape or a mouse that the cat didn't finish. They also get yogurt mixed into their ff sometimes. The county extension has been out here and they told me that everything growing on my place is safe for livestock. We have chukar partridge and ruffed grouse (from what I've been told) that live in the area and survive off of what is out there. We also have lots of little Gambrel's Quail running around thriving.
The mineral supplement I use is Azomite.
My daughter used to have some old english game bantams and in one of the pens she had a couple of cockerels and they would jump up onto her arms too.
Maybe perches in the run is the answer. I can imagine that it is amusing most days... unless you're busy or in a hurry.
