Not my first egg but the pullets first egg. You read that change will stop egg production. Wrong. It probably does but not this time. A friend comes to my farm & sees my chickens & wants some. We head to the feed store & he buys 2 Dominique's & 1 RIR pullets probably 6 weeks old. Then right at laying age tragedy hits. They disappear. I show up at his house & one Dominique has returned. I rescue the pullet put her in a cage throw her in the back of my truck for an hour are so ride to the farm. Forgot to mention I tell my friend knowing he has never gotten a single egg. I tell him I bet she starts laying. Yup I get to the farm get the cage from the truck & low & behold she layed her first egg in the back of my truck. Anyway even while she was a completely different color & the flock chased her pecked at her. The Dominique still layed eggs everyday & still does to this day. The flock she was introduced to consisted of 10 RIR pullets & 1 RIR cockerel. To say the least she was not accepted. I didn't quarantine her but I do recommend that others do. I Worried about my flock forever but got lucky.
