Just finished moving my 10/1 setting into the juvenile run. I moved 35, so again, a better than average brooding. I have my processing date for cockerels set for 12/9, and I am about to make a crude killing station for culling cockerels after that date. I am already getting 1st generation eggs, ~5/day, which from the 7 who are mature enough to possibly lay, is not bad. I have so far moved 29 pullets into my main flock. I re-homed 11 1.25 year-old hens, and will process my 12 3 year-olds on 12/9. That eliminates all my Generation 0 layers.
My next setting is on 1/6/16, which will make the cockerels old enough to be processed on the first day the processor is open next year (5/31).
My last 2 hatches have done well being put out in colder weather. I fed them more vitamin water than I had in the past (every other bottle of water during brooding), and I blocked off a corner in the juvenile run that seemed to lead to chicks dying due to being compressed. I haven't lost a single 3+ week old in the 4 days they've been outside.
So, shortly, all of my eggs will be 1st generation, and even better, there are now 3 BCM Roosters in the main flock to hopefully improve on my 75% fertility rate. I can't say all 3 are getting along (I have 1 who is just over 1.5 year-old, and 2 that are > 25 week old), but all 3 are unharmed.
I can tell the young pullet eggs based on their size (I get up to 55g, and then 60g+ eggs, the separation is due to the age of the layers), and there's an interesting phenom. About half of the eggs are very much darker than the other half. Still not yet reaching a darkness as shown on a BCM egg color chart (which goes from 4-10), but much darker than my average color from my original laying flock. So the plan is to incubate based on egg color...darker eggs yes, lighter no.
I am hoping to find an Ova 100, and sell my Octo 40, but I doubt I will have enough eggs by 1/6/16 to fill an Ova 100.
And for those who think hatching at the end of January is a bad idea (let alone hatching at the beginning of October), I am breeding birds hearty enough to survive my climate. In the next day or two I am closing up my runs to prevent cold winds and snow...so I am giving them an environment that should help. No heat, no insulation, but tons of fresh, unfrozen, water.
The experiment continues.
