Can a chicken who suffered from pasty butt develop slower that other chickens

[Firsttimehens1234]

On April 21 2022 8 little chicks hatch 7 of them come out normal but one of the maran eggs needed some help hatching but it survived.a couple of days later one of the 2 marans chicks suffered from pasty butt and was sick for 3-4 days and in that time it wasn’t growing so it ended up being a lot smaller than all of the other ones

as you can see in the picture the small one is the maran who suffered from pasty butt and it’s clearly alot smaller.

Fast forward to now and both of the marans turned out to both be pullets and is now 19 weeks old but they are so far apart in their development.

this is the maran who hatched normally and didn’t have pasty butt

and This is the one who needed to help hatch and had pasty butt.

As you can see there is quite a big difference so do you think it’s bc of the pasty butt and the couple days in her first week of life that she didn’t grow that caused the difference?

You have it backwards. Genetically flawed chicks usually have a much greater chance of developing pasty butt. They are usually smaller than the others from a few days old, and are known as failure-to-thrive (FTT) chicks.

Genetic abnormalities affect the embryo's ability to pip and successfully hatch . After hatch, they may lack organs that are developed adequately, resulting in poor metabolism. They require more heat due to poor calorie utilization, and growth rate is severely hampered. Pasty butt seems to accompany this syndrome.

Yes, it seems that pasty butt is a symptom rather than the cause of poor development. Both pullets look pretty healthy now to me.

Thank you for yours answer,they are both the same size now,but I don’t know if I should except her to ever lay eggs? Will she ever lay eggs?

If she's caught up in size, that means her organs also have caught up. She should be able to lay eggs, but we can't tell you when.

Thank you for your answer,I took a pic of both of them and I think they are about the same size do you?

The first pic is the one who had pasty butt and the second and third pic is the “normal”one(the black one in the picture)
