There are no limits to how many dragons you can keep on your scroll but there is a limit to how many eggs and unfrozen hatchlings you can have at one time. The base limit is four eggs and eight hatchlings, this changes with the increasing amount of dragons on a users scroll and their following trophy level:

1 - 49 dragons → No badge → 4 eggs/12 total dragons 50 - 199 dragons → Bronze badge → 5 eggs/15 total 200 - 499 dragons → Silver badge → 6 eggs/18 total 500+ dragons → Gold badge → 7 eggs/21 total

Previously, there was no benefit to badges, and you could have 4 eggs/8 total. Plus, you could breed a fifth egg making it 5 eggs/9 total.
