Hello Meghan and welcome to the family, glad you could join us and we look forward to hearing more about you and your grey Lucy.
I am sorry to hear you are having some troubles with Lucy but we will see what we can do to help you.
When you leave the room or leave the house do you answer her calls, she just may need reassurance that you are still around. When you do leave the house do you tell her you are going and where, some of them understand and react better to the absence.
Is she flighted? If so she could come with you if she wants to be around you especially if she has been left for periods of time, she is being a little insecure. Of course you need to ignore the noises so as not to be rewarding her for them. Praise her when she has been quiet for a period of time.
You will find lots of useful information in our many threads here, please read thru as many of them as possible and ask questions you may have. We will do our best to get you some answers and help you in any way we can.
If you have some pictures of Lucy you would like to share with us we would love to see her.
