One of my red foots has dig a hole in the enclosure and is acting really strange! She is sitting with her bum in the hole she dug pushing her head back and forth and there are some strange noises coming from in there. Hard to describe the noise but maybe slightly like a long popping noise but not really popping! The only thing I can think is she is laying eggs but she isn't very big and not sure what size/age they would be to so this? Neither tortoise has ever dug a hole before. I have sat up watching her as she was acting strange digging and I've not seen her do this before, although I haven't had them for long. What if she does have eggs but isn't big enough to pass them? I don't even know she's a she! Any ideas of anything else which would cause this behavior??
