So we have a mama who went broody and I couldn't get her to quit laying on the un-fertilized eggs. Got some fertilized ones from a friend, and three days ago they hatched, had a weak one but after some tender love and care it's perking up and on its way back to being where it's sibling chick is. (Only two hatched) QUESTION: I "candled" the remaining eggs (2) and saw right through one, and the other was solid black, tossed the un-fertilized one and replaced the fertilized thinking it needed another day or so to hatch. Three days after its siblings had hatched, it has not. Mama is still sitting on it, but I'm noticing her actually sitting off of it for a bit and only goes back to the egg when the chicks are sitting with the egg. HOW LONG UNTIL I JUST TAKE AWAY THIS LAST EGG? AND..... The way our coop is, I can shut the top part of the coop and they can't go down the ramp to the grass, I have had it shut since the first chick was born so they couldn't fall down the ramp (one already had) So mama and the two chicks are in the top part of the coop separate from the other four ladies. (The four ladies are free range and not allowed in the coop) The one very healthy chick I thought should prob start walking in the grass and pecking at the ground, so today I lifted both chicks to the ground inside the coop and let mama down. She almost trampled one because she was so mad that our dog was on the other side watching. (Both dogs are scared of our chickens) so I quickly scooped both back up and let mama go upstairs and shut them back in. What is the best way to slowly introduce mama and chicks to the grass again and should I just keep them like this until the chicks are bigger?! Not sure how to proceed best for chicks and mama. Thanks for your advice and thanks for reading my "book" of a question!
