Well, the elastic bands sort of worked. Only one feeder was knocked off over the weekend, and it retained its contents. On another feeder the band had snapped and was lying in the water container. It makes refilling the feeders a bit more complicated but as it seems to have saved a feeder of Nyger seed it’s worth it.
We had a blue tit visit the feeder I stuck on the window. It announced its presence with an irritating irregular tapping sound, which tends to suggest it might be a bit of a mixed blessing.
Out in the cherry trees down the drive Alasdair spotted a green woodpecker. We’ve had a bit of a chequered history with the species, having some good sightings locally but none round the centre. We hear them all the time and sometimes see something in the distance that flies like one but we’ve not had a good sighting. Alasdair is usually very good on IDs like this, so I added it to the list. A bit later I saw it too, as it rose from the ground and flew down the drive just as Alasdair had reported. Of course, I didn’t have my camera with me.
As I write this there’s more irritating tapping on the window. Julia says it’s a blue tit but as soon as I moved it spooked and flew off.
The keets are all keeping well, as are the two chicks that are in with them. We’ve called it a day with the eggs in the incubator as they were showing no signs of life and were well overdue. That’s what happens when you put dirty eggs in a dirty incubator. I know there’s a skill to it too (It’s not like the monster incubators we used to have at work) but basic attention to detail goes a long way to ensure hatchability.
There are around 17,000 pores in an egg shell. That is 17,000 places for a pathogen to enter. As the egg cools the contents contract and air and is drawn into the shell.
If your egg is laid in a dirty nestbox, or on the floor, the cooling process will suck in germs, which will find the mix of nutrients and warmth in an egg a very good environment.
When I worked in a hatchery we used to candle the eggs at 18 days and transfer them to a hatcher, which had a different environment for the last three days. It was dark in there, it was cramped and , above all, it was 37 degrees C (about 99 degrees F).
Just to add to the excitement, an egg would would occasionally explode when you pulled a tray of eggs out of the rack. These “bangers” were eggs that had incubated a full load of pathogens and, on being disturbed, burst under the pressure. When that happened we used to grab a disinfectant spray and mist the incubator in an attempt to stop a build up of germs. They used to work continuously, so there was never a time when we could switch them off. In fact those machines only stopped three times in 30 years – once when we moved them to another building, once when we programmed a major maintenance programme and once when we switched them off for the final time.
Anyway, backed to the cramped darkness and the stench of a burst egg. It wasn’t pleasant, and it was bad for the other eggs. Sometimes you could see this when candling as you could see a central egg and a spreading ring of eggs around it where it had infected the others.
And so, as my wife gradually draws me back into dealing with poultry, and into incubating more eggs, you can see why the feeling of doom is creeping up on me.
Two of the pictures are from today – the wet one with wheelbarrow and the red one with keets under a heat lamp. The others with poultry are from last week – look how the goslings have grown! Look at the way one of the parents (probably the gander) is thinking of having a go at me. He is going to end up with a shiny jacket and a couple of hours in a low oven if he isn’t careful.
The goats, looking like butter wouldn’t melt in their mouth, are planning an escape. I know that because I had to spend 20 minutes getting them back in the pen later that afternoon.
Great days! 😉
