Hey, grats on the new pickup!!!!

I would need to see a pic of the setup in general....but a few basic thoughts...

1. I would do your best to not have contact with the new pickup for one week . Do not attempt to feed till that time...and if they refuse do not offer till the next schedule feed time. For a young bp most fo 3-5 days....I personally do 3 days to start.

2. The reason they are behind the hide and squished leads me to think she is more secure back there. BP's like it tight....I am guessing that the hide is to big. It may also be a little bit of a heat issue, but more the likely she wants contact all sides. BP's in nature are vulnerable from attacks above. This is why they like full contact with the hide. Makes them feel head on top/back is protected.

3. 87 in general is too low for your warmside. You should shoot for 92-94 ish hot side and 82-84 cool. This will vary person to person with preference...but as you can see your warm side is close to what some would consider a cool side temp.

Again I would need to see the whole set up visually with everything your using but start with increasing temp, leaving her be, and tightening up the hide

Hope this helps, I am a noob myself so hopefully others respond as well
