I only have two fully grown chickens and one went broody, so put two eggs under her to hatch, the eggs had been in a incubator as i had given her half and put half in the incubator, her eggs were not furtial for some reason, so when two eggs pipped i whisked them under the broody. The broody was still in with the other chicken as i was worried one would get lonley and the other is kinnda broody, anyway i put one egg under each chicken, one chicken started eatting the shell and threw the chick out of the nest. so i got it back in the nest and put it under the other chicken. all goes well, next morning i check on them to find one chick looking dead and the other missing but cheeping. I find the missing one and the one i thought was dead twitches, so i give it a rub and it starts to revive over the next 45mins. I desided to move the broody inside where i can keep an eye on them to make sure mum is being nice. all goes well. but now i am wondering how and when i introduce the chicks and broody to the other chicken? I also have some older chicks who are about 5weeks old, who i would like to put in the group at sometime.
