Time for me to chime in with my feathery zoo!
I've got a bunch of eggs in the 'bators right now, and I've been going strong with hatches a few times each week since early spring. Just this last Friday and Sunday I hatched 14 Jumbo Coturnix and 6 Red Golden Pheasant (and one surprise Yellow Golden Pheasant). I also have over 110 Jumbo Coturnix Quail eggs, a dozen+ Duckwing and Shojo Ohiki eggs, 16 Exchequer Leghorns, a fistful of Blue Ginger Phoenix Bantam eggs, and I just loaded 9 wiggling-peep filled Schubert line Phoenix, 7 Ismer line Phoenix and a couple of ready-to-pop Ohiki and Bantam Phoenix eggs into my hatcher-bator.
I've already hatched out a small army of Bantam Phoenix, Ohikis and a few Standard Phoenix, untold numbers of Coturnix and Button Quail, and a handful of Red Golden Pheasants. PS: Most of the Bantam Phoenix, all of the German Phoenix and Ohikis are all from Aubrey at Boggy Bottom Bantams, so these are beautiful top tier longtail bitties here!
These are all shipped eggs from all over the country, so even taking the rigors of shipping/infertiles/temperature extremes/ random-???, I'm pleased to say that my hatch rate has averaged a solid 50-60% on over 700+ eggs of five different species and twenty different breeds of fowl this season. I have experienced the irritation of a 0/12 hatch this season (a bonafide Post Office Omelet, delivered directly to my PO Box! How ever so convenient! ;D), but I've also experienced the joy of a perfect 12/12.
My shipped egg incubation tools/methods:
I'm using all styro-bators (3 Hovabators and 1 LG; three air-circulated, one still-air, all auto-turned) in a temp and humidity controlled room (inside a central AC house set at 70 degrees constantly), and I put a dab of bleach in with the water that I fill the bators/hatchers with. I run 99.5 on all bators/hatchers with 45-50% humidity. The humidty/thermometers that I use are the newest models of combo hygrometer/thermometer from Incubator Warehouse, and I use two per incubator/hatcher, one right and one left side.
When I go into lockdown, I put each egg in a carton of egg-appropriate size (quail, bantam/pheasant, standard breed chicken) and load a single fresh sponge soaked in purified water. I've found that the putting the combination of a capful of bleach and water into any water tray (that will not physically contact a live chick... its not nice to let a newborn baby chick roll through even mild bleach water with open eyes) markedly reduced the 'incubator stagnation smell' and bacterial blood-ring deaths that you get with plain tap or bottled/purified water. My incubators are cleaned with Tek-Trol disinfectant between incubations.
I candle once every five days with a 300 lumen Fenix defensive LED flashlight (my rule of thumb for a 'good' candling flashlight: if at its highest power you can hold it under your fingers and see the blood vessels and bones of your hand, its a good one!) and remove any dead, oozing or infertiles immediately. PS: You will be able to see the difference between live arteries and dead ones, individual toes, and see a peep's heart beating perfectly with 250-350 lumens of light penetration. As a comparison, the standard LED lights sold for $5-10 by Incubator Warehouse average 30-50 lumens. Note: Coturnix/Button quail are still irritating to candle due to shell color/speckling/size and density... its like trying to peer through a steel BB pellet.
I've also found that hatching the eggs out in a similar position to how they were incubated significantly increased my live hatches. I suspect this has something to do with keeping chick positioning stable and ensuring that any excess fluid inside the egg is distributed towards the bottom of the egg (thereby preventing post-internal pip drownings). My brooders are kept right beside me in the house (in part so I can pick up on babies that need additional care but in part to socialize with my new feathered friends), and consist of two twenty gallon retired aquariums with two office desk lamp 60 watt bulbs overhead (one at each end).
Initially I use only pine chip bedding but as they age, I use pine chips and Sweet PDZ granule zeolite ammonia and liquid absorbing mineral (its sold as a horse stall freshener). Note: Day-olds will eat more granules than food if granules are introduced too early, so wait 2-3 weeks before adding granules. Everyone gets started off on Grow-Gel and hand-crushed non-medicated turkey/game bird starter (chickens get moved to other feeds as needed, all game birds stay on it). The aquarium tanks have screened metal lids for any early flyers.
I use empty 16 oz water bottles with a chicken nipple screwed into the cap end as their waterers (prevents water fouling and drowning issues with Button and Coturnix quail day-olds). I've experimented with leaving in a standard 'fount' type quail waterer and the nipple-on-a-Dasani bottle waterer with under 24 hour old Button and Coturnix quails, and even given the choice between the two, they always flock to the nipple waterer (I suspect that the reason why is that its more 'fun' to pick at the shiny silver tip than just tipping down into a plastic lip, just like how drinking with a straw is more 'fun' for kids than drinking straight from a cup). I've switched entirely from founts to nipples nowadays.
Happy hatching luck to us all! <3
