Buff Orpington L/F hatching eggs bought on e-bay

Wednesday, April 18th, 2012

21 days ago we entered 6 buff orpington large fowl eggs purchased and delivered from e-bay into our incubator. We stopped turning the eggs on sunday and today the first one has pipped with audible chirping from within. they are being left well alone for the next 24hrs, and hopefully more will start to hatch overnight.

These eggs were in the same incubator as the Marans and silkie eggs, so they have had quite a bit of open incubator time. I suspect our hatch rate may not be great, but 24 hrs ago I thought none were alive.

Does opening an incubator reduce the hatch rate ?

Wednesday, April 18th, 2012

I have researched this online and the general impression is yes, it can affect the hatch rate, even in the early stages of incubation. Commercial hatcheries certainly do not allow opening of incubators until day 18, when eggs are removed from turners and placed in increased moisture hatchers then not interfered with until hatching is complete, this is sometimes refered to as lockdown of the incubator.

It also appears that opening incubators to candle eggs at day 8-10 will also reduce success rates. Most hatcheries candle at 18 days at the same time as removing the eggs to a hatching area and stopping turning.

Eggs like a constant temperature environment with minimal fluctuations and an during the critical hatching period a reduction in the moisture increases the risk of the membranes drying sufficiently to harden and effectively trap the chick within the egg, unable to break out and hatch. Some hobby keepers suggest a sqirt of warm water from a mist spray if you open the  incubator to remove hatched chicks. It can take 30minutes to an hour to stabalise the water vapour levels inside the incubator compartment depending of the volumn and design. I suppose in theory incubators with larger heaters and fans stabalise faster, and those with digital control settings for temperature and moisture levels will be better able to adjust to sudden changes.

I have read reports of hatch rates dropping for 90% down to 40% with the only variation being frequent opening for inspection, candling and chick removal. these reports are all casual and there have not been any formal scientific studies I can find.

Silkie bantam hatch rates poor and delayed

Tuesday, April 17th, 2012

Starting with 12 silkie bantam eggs we were down to 9 by candling at day 10, one further failed to develop and was removed before the hatch, but a disapointing 4 eggs hatched and only 3 chicks survived the first 48hrs, one not making it out of the shell

Not a great hatch rate from 9 definately fertile eggs. I suspect the problem could be down to the eggs being in the same incubator as our maran eggs which, although started at identical times, hatched 48 hrs ahead of the silkies, resulting in the incubator having to be opened during the critical hatching period.

I cant explain the delay in hatching, all the advice suggested bantam eggs may be the first to hatch, sometimes from only 19 days incubation, but this seemed to be reversed for us with the 3 surviving silkies hatching on day 23

Cockoo Marans Hatch

Tuesday, April 17th, 2012

Over a 48 hr period we hatched 10 Marans all of which are doing well and now starting to grow wing feathers. They were moved to a brooder after 24hrs and have been followed by 3 silkie bantams which although they dwarf, are holding their own.

15 out of 15 Maran eggs developing at day 14

Saturday, April 7th, 2012

Candling Maran eggs is not easy, we found a 9 led bright light torch was needed to see anything. The light is cold so has the advantage of not heating the eggs during candling. Even with this bright light source only minimal detail is visible through the dark brown shell. All 15 maran eggs appear to have developing chicks which is a very impressive fertility rate. We should have the final figures this time next week.
