Have patience. Leave them for a few more days. You may want to candle the eggs to be sure they are viable. Candling means to shine a bright light into the egg and look for shadows or dark spots. If you are close to hatch you should not see any light coming from the egg. Many people make an error in the laid to hatch calculations. The 21 day calculation should be made from the day the incubation started not the day they were laid.
Your rooster may be sterile.
The act of laying the egg is natures way of ensuring that IF the hen is mated she can produce chicks. In the wild a hen may not have a rooster available at all times but will be capable of reproduction on the chance meeting of a rooster.
Yes. Stress will stop or slow egg production. The introduction of new flock mates or a new rooster will cause this.
The function of the rooster's wattle is in courting potential mates. It is an ornamental.
They are like birds, when a rooster mates with them they lay a couple of eggs and try to hatch them out. They will be laying for 6-7 days of lots of eggs and then they won't until a rooster breeds with them.
All roosters crow. But the crowing IS NOT what fertilizes the eggs. They are fertilized when the male mates with the female.
NO, that's like sayin if a bloke has sex with a baby the baby will have periods.
only if they would for you
Play hard ball, tell your mates he has a very small penis then get with one of his mates. OR Ignore him and if your mates are true friends they'll know to do the same.
Play solitaire.
after training period
yer, why not
Most likely there was a temperature or moisture problem. It is possible that the rooster has aged out and is "firing blanks" when he mates. You will need to "candle" the eggs to see if there is any growth going on inside the shell.
