I bought chickens about 20 days ago and there was not one egg for that time.
Yesterday I finally found one.
Today I find two.
Apparently, chickens need some time to start laying eggs.
I made sure to speed up the process by putting hay in coop so they are warm, making sure they have enough sunlight by letting them out early and having them be out until dark, feeding them a variety of foods, from chicken feed to wheat to grass and weeds and hay...
I even let them out of fence so they walk around where ever they wanna go and so they search food themselves as well.
I hope they start laying lots of eggs soon, because 3 per day just barely covers daily feeding expenses.
