Hi, Anyone send me the process of hatching eggs because i always fails in hatching eggs.
send images of babies day by day growth.

Are you trying to hatch your own eggs or eggs that have been posted to you? Eggs that have had to go through the post have a much lower hatch rate for various reasons, the biggest being how jostled about they get on their journey to you.

Make sure you have an independent, calibrated thermometer and hygrometer as the ones on incubators are notoriously unreliable. This article explains how to do this: https://www.backyardchickens.com/ar...incubator-thermometers-and-hygrometers.73634/

One of the biggest issues when incubating can be around humidity. It varies for every set-up and what works for one person may not be best for someone else. I've found weighing the eggs is the best way of tracking whether your humidity is in the right place or needs to be adjusted. You can weigh them all together with a gram scale then divide the total weight by the number of eggs you have to find the average. Plot that weight on a simple line graph that has the days from 0-18 along the bottom and the weight range you'll need up the side. Eggs need to lose about 12% of their weight over the first 18 days so work out what 12% of your start weight is (there are helpful percentage calculators online if you need them) and subtract that number from your start weight. This is the weight they need to be going into lockdown. Plot that number on day 18 then draw a straight line from your point on day 0 to your point on day 18. Now at any stage of incubation you can re-weigh your eggs and see if they are on track. By taking the average you can remove eggs that aren't developing or that have died without affecting the overall result.

You can also monitor the air cells inside the eggs but they can be loosened or even completely detached if the eggs have been posted to you, so that method is harder with shipped eggs.

Usually a humidity of 30-40% does the trick for the first 18 days, then for lockdown the humidity should be 60-70%.

Candling the eggs (shining a bright light into them) is a good way of seeing how incubation is going. It's very easy with white eggs but more of a challenge with brown (especially dark brown) and green/blue eggs. Here are a couple of articles that show the change inside the egg:

A consistent temperature is probably the most important factor when incubating. In a still air incubator (without a fan) the temperature needs to be 100-101F (38C), or in a forced air incubator (one that has a fan to circulate the air) it needs to be 99-99.5F (37.5C). If the room your incubator is in is a little cool or the temperature varies quite a bit wrapping the sides and base and some of the top with a blanket or towel will help keep the incubator temperature stable.

Ventilation is very important for the eggs. Some incubators have plugs that you remove and some have vents you have to open. At hatch the chicks need access to lots of fresh air so vents must be fully open or all plugs removed.

Hope that helps and feel free to ask any more questions.
