Hi everyone! I'm a complete newbie to hen keeping. We adopted 3 light Sussex hens 3days ago from what we know they are around 10 months old. I'm a bit worried as 2 have lighter combs and wattles than the other 1 (she seems to be the top hen) . All seem to be mite free and happily scratching at the dirt and foraging as well as drinking, eating their treats and feed. Could the stress of relocation be the cause of the lighter comb?
