Brought home 3 new pullets causing one broody hen the other sporatic laying

My small flock of 3 golden lace wyandottes was reduced when neighbor's dog killed one. The remaining two did well over the past year laying 6 out of 7 days easily producing a dozen med lg brown eggs. I decided to expand the flock and picked up 3 barnvelder pullets 8 wks. I've got the hens separate from the pullets but they can see/hear each other. Two weeks later one of the hens is now broody and the other laying sporadically. I feed the hens Feather Fixer and supplement with cracked corn and oats as scratch and a handful of oyster or crushed egg shells. So the hens are healthy. The pullets are on multi flock chick starter and they are doing fine as well. I'm expanding their run and plan to combine the flock within the next month. I check the broody hen several times a day and shag her out of the laying box - now when I call her name and tap the coop roof she knows what's coming and hops out. I also realize the addition of the pullets, even though separate, is a disruption, however, how do I get everyone back on track?

You will need to break you broody by putting her in a wire bottom crate elevated of the ground for 3-5 days, provide food and water. New members cause stress which will disrupt laying. In a week or two everyone should calm down. The broody is a disruption too so break her and expect less eggs for a bit.

Thanks. I had read about that as a remedy. How far off the ground does the cage need to be, enough for air circulation?

A few inches works, you just don't want the hen sitting down tight and heating up. Sometimes just moving them works, they will often pace, so be prepared.

Thanks for the advice. I'll post outcomes in a week or two. They all have personalities, each very different. Who would have thunk?

Hey everyone. Sorry to but in. I have a 2-3 month old jersey giant. Hen or cockerel? the jersey giant is the black ish blue one. The one in the middle is a black sex link. I put her up just for size comparison. Anything helps. Thanks!

They are a fun and delightful species, hopefully it goes quick and smooth for you.
