Our first flock did not have any noticeable pecking order until everyone had started laying around 6-7 months old. Then it went from 0 to 60. Butt feathers were being eaten. Chickens were rehomed.
My new bantam flock is the polar opposite. 17 weeks old. Non-stop drama, and no one's even laying yet. If two chickens square off, the loser is now subject to pecking and chasing by the winner at any and all times. They can't even walk past each other! It will eventually simmer down a bit, but then a new pair gets going and the cycle repeats. We're at the point where all toys and fun enrichment items (including an empty water bottle to peck at) have been removed from the run because THEY CANNOT HANDLE IT! Seriously, why are we fighting over a piece of plastic? One was even guarding the foot bath I put in on a hot day. A foot bath. You're afraid of the foot bath! Why are you chasing her away from it?!
Dandelion's afraid of Poppy. Poppy's afraid of Wren. Willow's afraid of Dandelion. Clover's afraid of Poppy. But then they'll all cuddle together and preen... assuming their positioning is right. It's like seating guests at a wedding reception.
Normal? Were the first chickens anomalies? Is every flock different in how they set the tone? Has anyone else noticed different intensities with different flocks? Any chance they'll chill out once they're laying eggs?
Let me know!
I could just say 'Tis the way of the chicken'. But that is not answering your question fully.
To understand why you have any sort of drama one needs to know how many chooks you have, and the size and nature of their housing. In addition to this would be enrichment and entertainment for them. Chickens are extremely intelligent, they need to have puzzles to solve and to be kept busy all the time, they are like 2 yr old children.
I have had similar discussions with others on another thread, in fact just last week we were discussing the dynamics of our flocks. Some had a clear hierarchy of power, other had a more organic flow to the hierarchy, and still another had not perceived drama at all.
The discussion then came around to free-range vs housed and what the nature of the flock was; also the size and age of the flock was discussed. The one thing that we settled on was that each flock was unique and had their own way of being.
For instance, my flock has ages from 8yrs to 8 months of age. I have silkies, a couple of OEGB Bantams, a Polish Roo, Orpingtons, and a bunch of plain old mutts. So it's a mixed flock of big and small.
There are at present 3 Roosters, one (the Polish) is at least 4 yrs old the other 2 (silkie and OEGB Bantam) have just turned 1 yr old. In total I have 43 chooks. They have the run of a 30 x 60 barn during the day, with horse stalls to hide in and dig around it, finding any bits of horse poop I have missed during muck out. There are places to run to, hide in, and fly up on, the most drama during the day is for that favourite nest box (brats!).
For a couple hrs in the afternoon they all have access to the front lawn area at the barn, and the escape artists do their thing and go out back and dig around in the manure pile (which trust me is extremely annoying as they have it all tore apart! Brats!). On weekends and holidays they are outside all day. There are no big spats or fights, just some subtle juggling for prime dust bathing spots, and sun bathing.
Winter they generally do not go outside, unless it's to the manure pile where it's warm - winters here are very cold with huge amts of snow (a chicken can get lost in 3' of snow hahaha).
What I have found is that the Roos have their favourite ladies, who tend to hang around them, all the hens move freely between all the roos. There is no clear line of leadership, one might be boss over another who in turn bosses a hen who will go and boss the first one.
The other big drama is bed time. The oldest ladies all roost first (smart girls as they get the best spots!), then the youngsters go to bed in groups. The Roos generally go roost with the oldest ladies - smart boys also get the best locations. When the youngsters finally go to bed the older ladies will make sure that they are not anywhere near them, the youngsters are relegated to the less favourable roosting locations.
Funnily enough I have found that when the hens get past 2 yrs old they start hanging out more with the oldest hens who are more accepting of them as they age. It's like us humans - all the elderly with hang out discussing things, watching the kids, and the teens are off by themselves doing who knows what. But once the teens get around 30 or 40 yrs old they start hanging with the elders. Isn't it amazing how animals and humans are so much alike?
If your flock has too much drama then maybe they need more enrichment, and a larger area, or some time roaming around outside. They need something to remove some of their energy, same as with a child or a young horse, they need 'work' and time to run around playing and wearing off excess energy. It's our job to ensure they have a way to do this safely.
