I do have a broody barred rock hen out in the main coop. I snuck a few of the silkie eggs under her this morning the ones I knew were fertile
What do you guys think I should do about my 2 broody barred rocks out in the coop. They are in nesting boxes full of eggs. I never kept track. I don’t know how old they are etc. There is probably a dozen under each hen. I’m predicting at oldest there are week old eggs and newer.
I'm not sure what is going on. How many broody Barred Rocks do you have? How long have they been broody? It sounds like you don't know anything about how old the eggs are or how long a broody has been sitting on them. Are they in different nests? How many chicks of what breeds do you want? Where are you, it would help to know how cold you are talking about.
There are a lot of different things you could do, you mentioned several of them. Any of them might work out. If it were me I'd get down to one broody hen, collect fresh eggs, and mark and start them. Keep it as simple as you can until you get more experience with a broody.
