Cyclical hormone surges are pretty normal with roosters.
As a side note, aggression as chicks is no indicator of sex. A couple years ago I had a couple of cream legbar chicks that would raise their hackles at each other and spar like roosters: wings out, pecking and kicking at each other. They...
The only time I've seen problems with new roosters or cockerels in a mature flock is one of two situations:
The roo is an over-aggressive bozo, in which case the hens may end up mobbing and killing him.
You introduce a young (under 6 months) cockerel wihtout a mature roo in the flock and he...
I have 3-5 roosters at a time with 24 hens and they get along reasonably well, but my flock free-ranges every day on over 4 acres. If it was me, I wouldn't add a second roo with that many hens in an enclosed space.
He could be a dud, or he could just be taking longer to figure things out. I have an 8 month cockerel that's eager but he's a bit of a doofus. When he tried mating one of my mature hens he took too long for her taste, so she just stood up and started walking since she was slightly bigger than...
Not with silkies, but I've had broody hens hatch and raise guinea keets without any problems. Granted this was in summer time (they hatched late June last year).
There's no way to really train them to not "go" wherever they go. Plus they'll try to dust bathe and dig holes in your lawn or garden. I have a lot of acreage and no kids, so it's largely not a problem. I just hose off the sidewalk between my house and garage every couple days, and I ended up...
To answer your question, no you don't need a rooster unless you're trying to breed chicks. I can't really tell from your posts if he's really doing anything bad, or you just find normal chicken mating behaviors upsetting. As far as the lack of egg-laying it could be from stress, it could be from...
They'll eat any kind of seeds you lay out unless you fence them off. I even made some cubes with PVC pipe and chicken wire for when I plant.
They also have their own peculiar ideas of landscaping. There's a couple areas in my yard they absolutely won't let anything grow in. They'll pick the...
Young or old, they'll sometimes get some really weird ideas on where to lay eggs.
I've had a couple go AWOL like yours did and pick oddbal places to lay eggs. A couple times a week they'll all decide they can only use one or two of the 7 nesting boxes I have for them, and then if one can't...
The "egg song" is actually either a location / escort call or a warning, depending on the situation and the exact rythm of it. My hens will use it to call for a rooster, or when they're arguing over nesting space. My guess is she was concerned over the strange bird she saw.
Quite the opposite. Initially she found them entertaining, when they got fully grown she's kind of scared of them. Different times she's tried to bully them but then one day one of the roosters retaliated: pecked and kicked her and chased her off. So these days she keeps her distance.
That...
They're not particularly long-lived animals even under ideal condtions. I had a hen that was over 10 years old and was pretty feisty until the last month she was alive, and I've got one old biddy that's at least seven years old and still laying eggs and keepign up with the youngsters. But those...
I've used automatic crawlspace vents to pretty decent effect. I set them up with a cross-draft and away from where the birds roost. They tend to open up fully only when it's over 70 degrees and they close up when it's 40 degrees or below.
If you're worried about heat in the summer, paint the...
