Three things to look for are:Thanks again, you made my night! My girls and guys are 4 months old. I am so excited, blue eggs soon! At least one of the boys is making a weak attempt to crow for the last couple of weeks. Now if my one maran turns out to be a hen, I would be ecstatic!
- combs get red (no longer a pinkish red) & may even grow a bit.
- they do "the squat" when you pet them; if previously feisty, you may notice some calmness.
- you may see them "try out" the nest box by sitting there & fussing with the bedding.
If these are your 1st chickens, then get ready for the egg-citement! Most hens have an egg-song to announce to the world that they have made an egg. I have one strange girl that does it BEFORE she lays an egg. She's also the first to join in when any other hen lays an egg.
Of course as chicken owners we do our own version of celebrating. ie: Take photos of the 1st egg & email those pics to everyone we know. (egg in the nest, egg with its maker, egg compared to a store egg - Probably the last store eggs you'll ever buy - BTW). And after a few days of admiring your egg, you'll finally taste it - but not before taking a few more pics of the egg on the stove.
