Well today I was sort of arguing with a person that pretty much doesn't know anything about chickens but has them... I asked if you were going to hatch chicks this year again. The person said "Yes but I need to find a different place other than the place were I got the last leghorn eggs from". I asked why? The person said "Well we ended up with to many boys" (like 7 boys and 3 girls). I told the person that it isn't were you get them from.. the hen chooses the sex of the chick(I believe). Then the person says " No thats not correct..it all depends on the temp. in the incubator, what your feeding them, and certain places you get them". I just left it at that. I tried to tell this person but whatever I said was false to them... I know this is not true I just had to rant a little... So to this person you can get more males or females depending on: Temp. Food that you are feeding the hen The place were the hens are at I'm sorry but people like this just make me mad...I've been raising birds longer than this person and I haven't lost as many.... ETA: I also told this person if there was a way to produce from female chick then hatcheries wouldn't have to kill so many rooster chicks and hatch out more than they need.
