No breeder can give you a guarantee of fertility. ■ how many live chicks hatched (hatching percentage)?
■ have they already hatched eggs from this mating? If you plan to buy hatching eggs from a breeder, ask them to give you an idea of how fertile their birds are: However, it’s really a very early death that’s not detectable.
#LOVE BIRD INCUBATOR CRACK#
If you crack it open after the other eggs have hatched, again you might class it as unfertilised. In this case, the egg will appear to be unfertilised if you candle it. This way, all her chicks will hatch within 24 hours of each other, around 21 days from the time she starts sitting. This clever trick means a hen can lay an egg a day for 5-10 days to create a ‘clutch’, but she doesn’t need to start incubation until she has finished laying the last one. The embryo will wait in suspended animation until incubation begins. In that time, the internal temperature should reduce from around 40☌ to between 12-20☌.Īt this stage, development ceases. The optimum time for an egg to cool down from laying until you put it in storage (or leave it in a broody hen’s nest) is six hours. It will measure 3-4mm across, and look like a round donut with a hole in the centre.Ī fertilised egg will slowly cool down after its laid, but the germinal disc will continue to grow, to around 5mm across, containing 40,000-60,000 cells.
By the time the egg is laid – about 24 hours later – the fertilised cells will have multiplied several hundred times.Ī fertilised egg has a paler, larger circle, with a pale-yellow centre. She releases a little sperm to fertilise each yolk as it begins its journey through the oviduct. When a hen is mated, she keeps a store of sperm inside her body, which can remain viable for up to 10 days or more. In an unfertilised egg, the germinal disc looks like a bright white spot, 1-2mm across. It’s a cluster of cells that will develop into a chick if the egg is fertilised. You can get a good idea of the fertility rate by cracking open a few eggs from a clutch (eggs laid 1-10 days after mating).Īll eggs have a tiny white dot on the surface of the yolk called the germinal disc. HOW DO YOU KNOW IF YOUR EGGS ARE FERTILE?
#LOVE BIRD INCUBATOR HOW TO#
Here’s how to narrow down what went wrong, and whether it was a fault with the parents, the egg, the incubator or incubation process, or the aftercare. Sometimes, the chicks may hatch but have health issues, or they may start hatching, but die before they’re out of the shell. You can also put eggs under a broody hen or use an incubator.īut the incubation process is a delicate operation. Sometimes, a mother hen will hide away and take the decision out of your hands. If you have a rooster in with your hens, it’s always tempting to hatch some chicks.
