That is good to hear that the bleeding stopped
About the problem foot...if you could post a picture of the foot your talking it would help to be able to see what your seeing.
Sounds like her feet may be in bad shape maybe due to not having the right type of perches for her feet?? It is good to provide different kinds of perches of varying widths and material (wooden, rope etc.) so that they can properly get the right excercise for their feet and thus avoid problems like this.
I hope this isnt the case but she could also be malnourished?? What kind of diet is she being fed? Does she eat veggies along with seed? Pellets? How is the other tiel doing? Are they male and female, always shared the same cage? Sorry for all the questions..hehe. I am curious
Are these your first cockatiels??
Even if these are not your first here is a really good website... http://www.cockatielcottage.net/
If it is your first pair of tiels you will find useful info I am sure you can use.
I am here too as well to be of help. I have 7 tiels (3 since they were eggs..hehe). I also have a pair of parakeets that are nesting and so far have 2 chicks hatched, 2 to go.
All my birds are tame and incredibly spoiled! I love them that way!
