So I am pretty new to this chicken thing and have a kinda odd question. So I have 5 roosters and 8 hens all in a decent size pen. Recently my husband and I let them start collecting eggs, and one decided to finally sit(it's been about 7 days she has been there now without moving).
Now she is still letting the other hens come and continue laying eggs in the same box she is sitting in(this just happens to be their favorite box to lay eggs). Anyways, a neighbor gave us a couple eggs to put up under her(about 2 days ago), and he told us today that his started hatching today!
Now my question is, if the eggs that we put under her(from the neighbor) hatch in the next couple of days...what happens to the rest of the eggs that don't hatch? Will this throw her off in any way cause she has been sitting for less than 21 days?
(There is also another hen that just started to share the nesting box and not moved for the last 3 days...in the same box!! Will she possibly continue to sit on the eggs that are left behind?!?)
