FB pages ghosted?

I'm working on 4 pages right now.
page 1, 2, 3 and 4.
The page 1 is already at 11k followers
page 2 is at 3k.

last week I started working on 2 more pages which are page 3 and 4

to make the last ones grow I was sharing their post on page 1 and 2.
Everything was okay at the start with only 1 share i managed to get almost 1k likes on page 3 and 400 on page 4.

after making more shares i noticed that posts shared from page 4 to the other pages were getting no reach and it's was only the page 4…
