I currently have a flock of 9.....1 RIR roo, 5 RIR hens, 3 bantams...all of which are around 30 weeks old and laying. I have them eating laying pellets, and also feed them scraps and a cup of corn scratch each day. I just bought a Brinsea incubator and am going to brood some when the weather warms up. I know that chicks can't eat laying pellets, but don't have room to expand coop to separate the smaller chicks (once they are born). Could someone please advise on how I should mix them in? Should I feed a flock maintainer with oyster shell free-choice, once the chicks leave the brooder and are put in the main coop/run??? Please give me some advise. Thanks in advance.
