Hi we have 2 6 week pullets, they are very jumpy and they will bounce around then stand up and jump at each other and jump ON each other (a pecking order fight) but it happens a lot, especially when they are outside with space. like multiple times an hour. they have been together for their whole lives, so it is no one new. We are trying to introduce a 3- week pullet but when they have these fights, both have stepped on her because she is so small and they are REALLY jumpy. HELP
