I haven't heard good things about these coops and hear they only last a few years if that. It is also cheaper to build your own especially if you have materials that you can repurpose. I'm building a coop that is based off the store bought ones and it has only cost me around 70 dollars so far to...
From what I read you may have to bandage it to keep it from reoccurring till it's healed but I'm not sure on how it's done and I can't find any links on bandaging it.

This gives good information on treating and what to do after treating. But you could also post on the emergency board and they would be able to help you over there.
Today was my chicks first time outside in the grass since hatching and they are loving it. They love finding the ants. Feel free to post your chicks outside.
Here the chick is today. I have had a lot better luck to night getting the vitamins down. I had to separate him because I walked over to the brooder and thought he was dead. Usually when I call for him he comes and he didn't move so I about had a heart attack but turned out okay thankfully.
I have been giving the chick as much vitamin E as possible I give it and selenium everyday. This chick is really stubborn though and refuses to eat the food with the vitamin E in it.
Was thinking of maybe doing something like that but I also wont be keeping them locking away at night once they get older. But I have some time to think about what the next step is to add on to the coop. Plus the wood isn't all that expensive for when adding on becomes necessary.
