Everyone's environment is unique and poses unique problems. I've been very lucky with parasites and bumblefoot, but there's very little forage.
I did say that, but then I recalled my plan to expand the flock every two years (Katie and Edie were in the second expansion after a failed hatch). So it's either another hatch when Ivy turns broody or pullets. Like Mary, Ivy's not getting any younger and she did a great job incubating the chick Peggy killed. So she can have a few eggs when she goes broody.
If both hatches fail, I'll get a trio of pullets and they can quarantine in the spare coop (which would be a big improvement over last time when pullets quarantined in the back room!)
Where I live, they're called staples.
I keep catching them with the magnet
She usually takes a huge jump onto the ramp but last night, she took a small jump and fumbled the landing. Not like her at all.
It's still a struggle to single out a hen. I prefer to give everyone special meals and that's what I've done tonight. They're finishing up their dinner bowls while I write this reply. Sardines blitzed with pellets, grain mix and a little chick crumble.
Heavy metal toxicity is a problem in most fish predators I believe because they eat the smaller fish who carry smaller quantities of the metals. We're lucky in Australia because the tuna are smaller (but packaged the same I believe). Smaller fish carry fewer heavy metals, so the same sized tin of tuna is not as harmful. Someone worked out an Australian would have to consume something like 40 cans of tuna a week to run into health problems.
I doubt anyone has done the sums for chickens eating tuna.
