We adopted six chickens just a few weeks ago, not knowing exactly how old they were or much else about them. We guessed that they were about four months old and might start laying in another month or so. After being in isolation for about a week, we integrated them with the rest of the flock and they seem to be doing wonderfully.
You will understand my surprise when I found this tiny egg in one of the nesting boxes the other day!
It's difficult to tell size without something for comparison so here it is next to a regular egg.
I guess we were a little under in our guess of the age of those birds. How exciting! We may be getting more eggs sooner than we expected.
