Daily weight gain in layer chicks

[Jetpad]

I decided to start weighing my chicks using a digital food scale (but missed the first day I had them) just to help identify any early development problems. I have six different breeds and I think I've identified them all correctly although the Cuckoo Maran and the Barred Rock might be switched. They all seem to be growing well except for possibly the Cuckoo Maran. The only weight charts that I could find showed the day 7 weight should be about 70 g and the 14 day weight should be about 115 g. I assume those weights are for production layers and not these breeds. Do these weights look about right? Are Cuckoo Marans slow growers? Are Barred Rocks fast growers?

Daily weight in grams.

I measured my chicks until they were almost 2 weeks and then I stopped, but I weighed them in ounces. So it'd be hard to compare their weights to yours. I have a Australorp, Black sex link, Brown sex link and Silkie. I also weighed my two mixed breed chicks at the same age and they were the same weight as the sex links.

Here are the same weights in ounces if it helps.

Here's an update to the weights (in grams) in case anyone is interested in comparing to their own flock. My Cuckoo Maran still seems to be gaining weight about a week ahead of the others and the Barred Rock is about a week behind.

OH! I couldn't find the notebook I wrote the weights in, but I'll try to find it! Wow! They grow a lot in just a few weeks!
