That’s a lot of extra work plus she will had egg shells in her yolks. I like your paper pots much better.
For everything else I would just crush some eggshells to put near the bottom of the paper pots, or just wait and throw them in the hole when transplanting the seedlings.
We actually bought one of those wooden pot makers on sale at the end of last year. We used them this spring they were great.
Still no significant rainfall. Trees are getting yellow leaves and dying. Still hauling water for fruit trees and other perennial fruits and veggies.
Hauling in about 45 gallons every two or three days for some of my heirlooms and perennial herbs. Especially concerned to get at least one good ear of corn for seeds next year,since corn seed doesn't remain viable for long, plus it should have some tolerance for drought maybe LOL.
Have a great weekend. God Bless.
