Retarded growth of 5 weeks old chicks.

[GhettoRoo]

Hello. So, from one brooder with hen I have 6 chicks, 1 is hatched, 5 bought incubated ones.
Mine chick when will be grown up should be around 4 pounds, 3 retarded around 7 pounds, but now they are 2x smaller, like normal chick in 2-3 weeks of age.

They are Russian orloffs.

Is there any suggestions?
Mostly not acting like sick ones, but from that brooder, have the most deaths.
Guess because I bought them just hatched, and vaccinate in my home, not as others, which I bought 2-3 days old for other hen mothers and they was already vaccinated in they home.

So.
6 chicks
One mine is really healthy.
One more, guess Brown Leghorn is good too.
White leghorn too.
One of Orloffs too.
But two is small, gonna post pic later.

There you can see him right next to hen, back to hen is other Orloff, but with darker colouring, and next to him is one other little one but more mobile. There is Light Leghorn, And with chest forward to us is mine EE blood chick.

And these is only one week older. One in the middle is Orloff too.

Did you buy the eggs, or are they natural? It's possible you could have bought some bantams by mistake.

I bought them as 1-3 day old chicks.
Today one was really weak, couldnt even make a noise. Second one es still little bit retarded, but hope to get him back to life, survive his pain.
