Can anybody tell me what spiders these are?
An unusual egg sac and the eggs are about to hatch. The slings are just too young to identify.
No, there was what appeared to be an adult spider in each compartment.
These would be some type of social spider, inside of their sac there is just no detail for an ID. Perhaps a photo of one out of the sac.
It looks like they are black footed yellow sac spiders in the genus Cheiracanthium….what I thought were egg sacs when I first looked at the picture…are actually their fat yellow abdomens…..they seem all to be female judging by their shape so they may be about to lay eggs…or they may be just hanging out in their sleep sacs during the day …as they do….if they are protecting eggs already laid….they can be aggressive

I was leaning toward the black footed yellow sac spider too. I just couldn’t find any other pictures of them in a “colony” of sacs. Thanks.
Thanks for posting the photo! This is really interesting. 🙂 The Chieracanthium spiders in my house sleep alone. They usually make sacs in the groves of doorway molding and wall corners. There are 2 species in the genus in Northeast US. One is native, the other is introduced. My indoors ones are pale or lemon yellow with clear pale legs. The outside ones ( maybe C. inclusum) are larger and darker, the have tints of brown, green, or blue.
