I've searched all over BYC, and can't seem to find an answer to a few questions about hatching. Last year, I hatched out two batches of chicks under broody hens. 1st batch - set 6 eggs; 3 hatched - two roos & 1 pullet; eggs were from 2 Red Star hens & 1 Easter Egger hen 2nd batch - set 9 eggs - 7 hatched - 5 roos & 2 pullets; eggs were from the following with the resulting gender: 1 Wyandotte = roo 2 EE (not the same hen) = roos 2 Black Star - only have one hen = both roosters 2 Partridge Rock - only have one hen = both pullets! So, obviously, I did not get a 50/50 ratio, and I've read many others have experienced this too. My "theory" is that I got more roos than pullets, because I only hatched out 1 or two eggs from each hen. 1. My first question is - What's the best way to get a 50/50 ratio when hatching? 2. If I want to hatch a total of 42 eggs - and get an average of 18-20 eggs a day, would it be better to ... A. Hatch two or three days worth of eggs - obviously selecting the clean & normal shaped eggs; B. Or hatch 6 days worth of eggs from only a few hens - try to select the identical eggs or those that are from the same hens. Therefore, you'd end up with 4-6 eggs from each hen, thereby increasing your chances of getting a better ratio; 3. Does the 50/50 ratio apply to each individual hen - as in one day's eggs will be a roo and the next day's a pullet? Or not? A. For example, I have certain hens that I can tell their eggs apart from the others. If I were to hatch 6 days worth of eggs from that particular hen, would it be more likely to get a 50/50 ratio from those eggs? B. What if I selected 2 eggs from 21 individual hens for the total 42 eggs to hatch? Would it be more likely for the ratio to become "unbalanced"? If anyone has experiemented with this, I'd like to know! Thanks.
