Here in NY the preserve pheasant season goes until 4/15.
The suppliers still have birds because of the harsh winter, a lot of releases were canceled. We have been told that the breeding season has started, cock-birds are killing each other and the hens are gravid (have eggs).
I have been told that gravid birds will fly just fine (that from the suppliers that want to sell birds now).
OTOH I have been told by some hunters that late season hens with 2-3 eggs in them don't fly well at all and the dogs will usually chase them down.
Any experience with this?
