Hello, I have one couple of lovebird that currently are feeding their second clutch of chicks , they are 5 weeks already all good both parents providing food for them, however, I noticed yesterday the female being aggressive to the male. I thought if she keeps acting like that will need to put in a separator is possible to divide the cage in two. Today when I’m at work she bite his feet and blood all around… Do anyone knows why? They never did that with the first clutch. I already separate them… any recommendation?
