Ariel is acting really strange. she had one kit two days ago (baby is doing great) mom is feeding baby and she herself (ariel) is eating, drinking and pooping just fine. But, when I put the hay in her cage she instantly scatters it all over. She normally loves hay and will start munching right away. Also as soon as I open her cage she tries to get out! She has never been like this before having her baby. Is this normal? She is usually very calm. is this something I should be worried about?
