Great question. I have two Jersey Giant Pullets recovering from injuries. They get along but one is dominant. Marsala will eat and drink her fill before Anna can approach. Marsala will walk away then Anna eats with no interruption. They seem to spend equal time at the bowl yet Marsala weighs near twice as much as Anna. Both are healing well , are perky and active, and other than the occasional reminder who's boss, there is no fighting. They both love to perch on me when I lay on my side. Anna, the subordinate, does aggressively enforce one Rule...SHE, perches on my ribs, close to my armpit! Anna raises Hell and pushes past Marsala if she settles in to high up...JJ
