My Parakeets are named Sunny and Misty and they seem to be ready to lay eggs. They have been mating and preparing the nest for a few days now but the last couple of days Sunny (the female) started acting very creepy. A couple of times every day she leans forward, sings weakly, her behind opens up and she tries to lay an egg, her eyes look hypnotized, and she doesn't seem to be able to sense anything. A couple of times when she did it I looked inside her behind but it just looked like an empty pink hole. Other times she will sit on the perch with her feathers tight up against her body and she holds her wings a little away from her self and vibrates them. Something seems very wrong with her but I haven't been able to figure it out. Can you help me?
