Why was my hatch rate only 50 %

Huh, that’s strange then

Yeah I don't know what the problem is.

No they were from my flock that has 3 roosters and they were all developing fine in the first few weeks.

Sometimes the parents diet and genetics affect fertility.

What was your temperature and humidity? Were the eggs dirty when you collected them?

its usually temp if alot start to develop and die .. be sure to check it late at night early in the morni g and high noon as the ambient temp swings .. if its fine at one time of day it might be several degrees out if the ambient temp swings alot esoecially this time of year .. like here its still cold at night but 80 sumpin in the day so the house temp varies alot, it can affect the bator temps, so .. be sure to check the stability .. common practice for me is to cover it lightly with a towel and have it located in a non drafty corner somewhere .. the central air banging on and a big draft on it may swing the temps alot also ..

The temp was 99.5 and H 48-55% and the eggs were clean.

they were fertile on like day six but then after I opened them up and lok they looked like they died on day 8-12 ish

So check out my favorite hatching resource.. it has possible cause of embryonic failure according to what day they quit, starting around page 51..

Long and technical.. but hope it helps!

The temp was 99.5 and H 48-55% and the eggs were clean.

Consider going lower humidity next time.. closer to 35-45% for the first 18 days. Then 55-60% for hatch. What breeds are we talking about here?

Breeder diet. Sometimes even an individual hen will require more nutrients than the rest of the flock, (if you KNOW your nutrition is spot on) to produce viable HATHCING eggs. Egg storage conditions, breed genetics ( excessive inbreeding), lethal genes like double tufting (most folks know they have these type of birds) , age of flock. What your feed routine including treats and supplements?

Some breeds have lower viability than others.. I had the hardest time getting white faced black spanish to hatch despite mix breeds getting 100% and other pure breeds getting in the high 90's- 100%.. (suspected limited gene pool).

But HEY, eyes on the prize.. congrats on your first hatch!

Pics always welcome!

I would try dry hatching. I dry hatch with the same incubator and my hatch rates went up considerably. My last batch was 100% hatch rate dry hatching.

Thank you for posting this. I've just printed it out and bound it, so I now have a ready reference book. I've already learned some things just scanning through it while printing.

Ok I will do that for the humidity. The breeding flock is from Murray Mcmurray hatchery and so they are pure breed but I have three breeds in my flock and I just hatched a barnyard assortment of eggs. I feed the parents Homestead All flock and give them some hen scratch and some meal worms just about everyday.
