Pigeon

Question
I have some pairs of pigeon. Recently one pair of them laid
two eggs. After 14 days they eat their eggs. before it they
didn't sit on them. but we took care proper . So why they
didn't sit on their eggs and eat them?

Answer
Without more information, there are a lot of reasons this could happen.  Most likely they are either young or being disturbed by something; such as vermin, people, dogs, etc.

If they were mine, I would seperate the pair and mate them with other mates and work from there.  That way you can at least determine which is the problem.

Occasionally, there are personality conflicts with pairs!  Not common, but it does happen.

At the very least, I would seperate them for the winter to prevent further attempts.  Then return them to the breeding loft next spring.  Mother nature has a way of correcting things sometimes!!
