I wanted to give a very good example of how different snakes grow from each other.
This is Echo my cinnamon yellowbelly. She was born August 2, 2014. Today she weighs 829g.
This is Rain, my Mojave. She was born August 22, 2014. Today she weighs 189g.
Here they are together. It is amazing to see the size difference.
Rain (Mojave) would not eat as baby and was being tube fed by the SPCA's vet. At 4 months old she finally ate a live ASF for the first time but she would still only eat once or twice a month. At 7 months she was finally showing more interest in food. She now eats successfully once every 5 days. Se should bulk up pretty quick but this is a pretty good example of different growths in BP (and pretty much all other snakes out there). I adopted her and was amazed at her extremely small size, almost not believing the age the SPCA told me. The SPCA "guy" showed me charts of Rain's siblings. (Apparently the mother was a surrender and was egg bound. The SPCA has no information on the sire so who know what this little girl is full of). The siblings were much bigger then her even at hatching. She 36g when she hatched while her siblings ranged from 60-90g. But there you go. She is very healthy now and is growing like a weed. When I got her (last month), she was 126g.
