Very possible. They should all have space to roost plus some extra. They will jockey over the highest place or "most desirable" place. Generally, the best place is reserved for the top dawg. Don't fret if they don't take to it right away, sometimes it takes them a little extra time to get used to it.thank you so much for your reply and everyone else as well i give my hens treats from the gardens as well and they also free range i have 35 acres they can wonder the whole thing if they like but they only stay 100ft from the coop i think i learned why there not laying from a youtube video but it could be wrong, i only have 1 roosting spot and its not big enough for the full 17 hens the rest sleep in the corner of the coop. The vid i watched said that stresses them out and they have to fight to get a spot which could prevent eggs so i built 2 more spots yesterday so now they have plenty of space and i added to more nesting boxes hopefully that will be enough guess we shall see.
