A patio does sound nice! And that's good she doesn't go after big chickens. I think ours must come back every spring too because I don't hear them in winter. Except she only just recently left. Unless they leave the babies to find their own way? Cause they migrate right? I'm not sure we could handle keeping them inside that long haha and yeah, crows can be annoying but recently I've also seen so many posts elsewhere and stories/articles about how intelligent they and other birds in the family (corvid, I know it includes ravens and I think jays but not sure what. Else. Crows and ravens are the smartest) so I've definitely come to like them now haha I'm not sure ours keep them away considering the hawks still come back but I've seen them chase them. Sometimes just one,often two or three, chasing the poor hawk all over the sky and making tons of noise LOL I think the hawks must go after their eggs or chicks or something. They sure keep them away though. Haven't seen it in a little while though.
But oh wow, that is getting slow! I should probably add one too when they get older but I'd probably get maybe two so they're not alone for integration. You've never had issues?
I think the wild bird populace all hatch their young in the Spring including hawks, crows, sparrows, doves, hummies, etc etc. Other than the wild escaped parrot populations from the L.A. Arboretum we don't see much birds in the winter other than a couple resident hummingbirds and flying rats (annoying sparrows). Some wild avians stay through our mild fall/winter season but the wild birds chase off their offspring to diversify their own gene pool - smart eh? The mother hummies will tolerate their fledglings for a couple weeks aroiund the hummie feeder but then chases them off to find their own territories.
We went through 13 chickens to get down to the 4 girls we have now - some were re-homed cockerels, some were re-homed bullies, a couple died young, one had to be put down. I'm sorry to say that the cockerels, young deaths, and the euthanized bird were all from breeders who shipped the wrong sex or sick birds to us. The 4 re-homed bullies were my mistaken choice to put with docile breeds.
I came from a 25-acre farm where there was no limit on livestock/poultry but in retirement our cottage is zoned for only 5 hens/no roos. So I have had to learn how to integrate a single pullet into an existing little flock with as little drama as possible. The key for me is to have only non-combative docile breeds to start with. I put the new pullet on one side of a rabbit fence outdoors while the flock on the other side see her for several days. Then I screen a nest in the coop so all wake up in the morning seeing the same pullet. Eventually we remove the screen in a few days and let the girls sort out their pecking order which has been amazingly mild with docile breeds like our Silkies, Ameraucana, and Breda.
I'm not keen on lethal-gene chickens like Creepers (Dumpies) or Araucanas. But if my Ameraucana won't resume her blue egg-laying this winter then I may have to resort to getting a little Araucana for blue eggs - a lot of Araucana breeders have to cull rigorously to get SOP so there are a lot of pet quality available with flaws but still lay the blue or blue-green eggs somewhat steadier than the Amer's or EE's - at least that's the feedback I've been getting. But if my prima dona Amer decides to finally start laying again my next breed then will be a Dominique (we had a Dom before and really liked her but was one of the pullets that died too young).
It's an adventure with chickeneering and you never know what surprises or adjustments come your way!
