@Sally Sunshine since this is an incubating thread I'll post todays incubating question. When doing the whole lockdown thing on Day 18. Does it matter when on day 18 you candle and raise humidity? Also what humidity should I try to obtain?
anytime, and if your air cells look good on standard eggs raise to 65-70 if they still need a tad to loose go 60 until you see externals, if they r too big go 70-75

you saw my calendar right ? no clue if I set morning or night, never mattered as long as they are locked day 18 before internal pips, bantams may wanna check day 17 and run humidity 70-75% esp serama.

So sometime on day 18 candle them, remove auto-turner and raise humidity. right? Than don't touch until the little boogers start making there grand entrance.

and put something over your wire, and be sure chicks cant drown in water dishes, use sponges or shamwows

SEE the "lower temp during lockdown below" if your thermostat isnt so touchy and read this again on marking prob pip area setting up.



Candle day 18 is to determine growth, weigh, pencil mark air cell size and dispose bad eggs. It will look pretty dark and FULL in there! You may or ma

y not see movement on this candle. Its ok if not, don’t panic! The chick may easily be resting! See how that air cell is beginning to dip more to one side and if you lay the egg down it will roll into the hatching position. I set my eggs with lowest dip in the aircell up. This position for hatching is good so the chick is able to turn into position and I can easily see my pips too! Day 18 laying horizontal for actual hatching helps a chick hatch 1-2 hours earlier. I lay my eggs down LOWEST DIP of the AIRCELL UP! This is the normal and most likely hatching position and the chick will break through or Internally pip and externally pip in that probable area. See the image below with the x, x being lowest dip in air cell and probably pip area/s.








LOCKDOWN!
Stop turning, Remove Turner and Raise Humidity to 65% - 70%
depending on what your air cells may still need


NOTE LAY AT HATCH IF POSSIBLE!!
HOWEVER, SEE further BELOW FOR SHIPPED EGGS OPTIONS
It is now known that the different embryos communicate with each other by a series of clicking sounds,
the rate of clicking being the important feature. Ensuring the eggs on the hatching trays are in contact with each other facilitates the synchronization of hatching where the eggs are incubated in a modern machine. This assists in reducing the time between when the first and last chicks hatch.

SHIPPED EGGS!!
LOOSE AIR CELLS MUST BE HATCHED UPRIGHT!!

MALPOSITIONS and SADDLE SHAPES
Saddle shape could cause them to not be able to turn to pip and be malposition, some mals do pip and get out. in a carton what are their chances if they pip against the carton where you have them setting? any shipped egg that has survived to day 18 for lockdown can be layed horizontal down to hatch... their are plenty of facts to back up what I have written in the article should you research yourself.




After Day 18 candle you will “LOCK DOWN” your eggs. Lower the temperature see suggest temps below and increase the humidity the last three days. STOP turning and the incubator stays closed, for the next three days while the chicks hatch! If you’re having a hard time with humidity it is OK to open quickly to boost, add warm water or increase the size of the pan or add a wet sponge. NEVER ADJUST HUMIDITY BY cutting back airflow. VENTILATION is EXTREMELY important at this stage!

Researchers have found that lowering temperatures will prolong incubation,
HOWEVER it is favourable to do so at the end of incubation.
Day 19 & 20 Temp Min 98.0 Max 98.5
Day 21 Temp Min 97 Max 98.0

A REALY GOOD READ
on what that chick is doing in that egg at this time!

Development of motor patterns in avian embryos:
hatching behavior http://www.int-ornith-union.org/files/proceedings/durban/Symposium/S46/S46.1.htm

A GOOD IDEA FOR SOME STYROFOAM INCUBATORS
COVER THE BOTTOM WIRE GRATE with A SMALLER TYPE OF SCREENING
CHICKS can get broken legs in these large sized wire grates
EXAMPLES Window SCREEN, or DOLLAR store rubber Shelf mat with the holes
see below:

Note: foam grip drawer mat on the wire bottom of incubator on day on day 18 lockdown. A cloth, crinoline, or paper towels could work as well. This ALSO protects the navel, the place where the abdomen closes after surrounding the remains of the yolk, from injury. It also makes cleaning the incubator easier. NO the wire on the incubator bottom should not injure or effect your chicks after they hatch. Dollar store baskets are great to keep hatching chicks separated by breed.

YOU CAN USE A small plastic salad dressing cup, duct tape the bottom to keep it from toppling to hold single eggs upright!
