Well.... it depends how long its been in the egg. If its been 1 month take it to the vet.
Usually spring, but some birds of prey begin courtship in late winter.
Pheasant eggs typically hatch in late spring, around May to June, depending on the region and environmental conditions. This period coincides with the spring season, which provides favorable temperatures and abundant food sources for the chicks after they hatch.
You should not do this. The eggs that are already there will hatch much sooner, the hen will continue to set on them but the older chicks will bully the late one's and often kill them unless you separate them. Eggs only take 21 days to hatch so if your hen has been on the nest continually for 10 days you are too late to add eggs.
Sounds like a late hatch. Most chicks hatch at or around 21 days but there are reasons they may hatch at 23 days. I just had two hatch from a clutch of eggs on day 24 and they are Araucana's.
late February
Peregrine falcon eggs typically hatch after an incubation period of about 29 to 32 days. Hatching usually occurs in late spring to early summer, depending on the geographical location and environmental conditions. The chicks, known as eyases, are altricial, meaning they are born helpless and rely on their parents for food and care.
In my experience using Silkie Broody Hens, you do often get two sharing the brooding, and happily share the parenting. I've never had these hens kill chicks, quite the opposite, they are both very protective of them . Of course if you have a new batch of eggs you want to hatch move one broody hen on to them and she will sit. Hope this helps
It is unlikely. Not beyond hope but most eggs will show some sign of pipping all about the same time. After hundreds of hatching here, we generally do not bother with eggs showing no sign of hatch after 48 hours. If all the other chicks have arrived, the late babies will likely be too weak and small to survive with the older,stronger chicks anyway. Try getting a candler to use on late hatch eggs and look for movement after 24 hours.
Baby emus typically hatch about 50 to 56 days after the eggs are laid. The male emu is responsible for incubating the eggs, which he does by sitting on them to keep them warm. Hatching usually occurs in the late spring to early summer, depending on the region and environmental conditions. Once hatched, the chicks are precocial, meaning they are relatively mature and can walk and feed themselves shortly after emerging from the egg.
She's lazy.
Not always. Late hatch can occur if the temperatures or humidity are not right in the incubator or if the broody hen has left the clutch for any long periods of time. It is always a good idea to candle the eggs on the 21st day and see if there is movement. Leave the eggs an extra day or two if you feel they may have life in them. If hatching with an incubator, bump up the humidity to +60% for the late hatch.
from late summer to spring
