I know I’m random but I have thought about trying this for a while. I have got 6 fertilised eggs from someone who has chickens and a rooster (both needed to make an egg viable). I don’t know if it will work. I’ve got them in my warmest room and later (they have to settle after being in the post for 12 hours) I’m going to put them in a box with padding around them. The cats won’t be allowed anywhere near them especially when they hatch. I will need to sell them to those with chickens who has a garden when they’re fully grown. I don’t think house chickens will go down well with my landlord. It’s okay when they’re babies but chickens can end up quite large depending on what breed they may be. There’s definitely more than one breed in the selection as there are two different egg types in the box.
