I have hatched out a few clutches that frankly the genetics was a little iffy. If the chick was pretty small out of a fairly small egg sometimes the process of growing just takes on a time line all to itself. We have hatched out Bantams, blacktails, saramas and a few other small breeds. Some of these chickc were just tiny. You may have an instance were a questionable pair of chickens mated and produced something you are not thinking would come out of an egg. I have a few silkie/leghorn mixes. They are cute as can be, but they are more leghorn than silkie. On the other side of the spectrum we have a few Bantam/silkie mixes. Now these are cute little chicks, but they are TINY. Yes, someday we will have to seperate them, but in the short run we will not incubate any more "questionable eggs". We did have fun though and they will all have a nice home. We hatched out one that was unidentified until it got to be about 3 weeks old (I got a bantam/wild red jungle fowl) cute little sh-t. I also have a few other red jungle fowl that are not true to the breed. I will sell these to people I know that want eggs only. The red jungle fowl hens are prolific layers and the eggs are nice big brown ones. The roosters are more " lawn candy " than anything else, people just love em, they are gorgeous.
