Day 102: How long do Gila monster eggs incubate?

Mark Seward says 124 – 150 days. I am at Day 102 and it’s hard to be patient. Six eggs remain in the incubator and I have not touched them in some time for fear of creating a problem that didn’t exist. The Grumbach has done an admirable job of keeping both temperature and humidity very stable, and the S.I.M. Containers are keeping the eggs … Continue reading Day 102: How long do Gila monster eggs incubate?

Update 5: Waiting is the hardest part

Not much has happened since the last update; one good egg died leaving me eight healthy growing eggs in the Grumbach incubator.

Why do Gila monsters play dead?

He called in a panic and said that my pink lizard (his reference of Gila monsters to this day) was dead. Of course when the cage was opened the lizard sprang to life and was quite aggressive upon examination. Now … Continue reading Why do Gila monsters play dead?

Joy’s pain: a Gila monster’s road to recovery

When I purchased the six Gila monsters, No. 6 (now known as Joy) was the only one that looked a little off; she was skinnier than the rest and her fat reserves in her tail were depleted. I thought it may have been from overwintering but that was not to be the case as it quickly became apparent she was sick. She excreted a red … Continue reading Joy’s pain: a Gila monster’s road to recovery
