Well it it's not nature in the 'wild' sense but it's certainly natural. We have chooks and ducks nesting all over the place in the backyard at the moment. These ones just hatched this morning.
All but one of these are Silkies. The last shot is an Old English Game bantam. The bantam has been sneaking eggs into other chook nests. Perhaps there are some Cuckoo genes in there somewhere :-) In any case it is the best looking bird of the lot but unfortunately it is also the weakest and seems to be having trouble standing. Time will tell.
