I have two things to ask:
1. I have baby finches now almost covered in feathers, 4 of them. Still in nest atm. The mother and father are picking on another lone male who's partner died last week and i had to throw the eggs away. Its more so the mother female finch picking on the lone male, why is this happening? She chases him all over the avery!
2. I noticed the father of the babies has injured his wing today somehow, its sitting lower than the other wing and he isnt flying very well. No idea how this happened but is there anything i should do? Due to the female that died last week, i thought she had mites so i sprayed her and brought her inside, im not sure what killed her, the mites or me spraying her and bringing her inside

Thank you in advance for any replies..
