My little silkie eggs were rocking nicely the last 2 days and last night they stopped. I checked today and still nothing. I can't hear them due to the fan on the incubator. Did they die on me? Is this normal? What do I do? Should I pull one and see if it peeps? This is day 20 for me so I'm still in lockdown. Please advise. Also my humidity has been dropping so I put the vent plus back in and added paper towel so I can be around 65-70 is that ok?
