I just picked up 3, 2 day old chicks on monday (Rhode Island Red, Cochin Splash, Cochin Sil Laced) to eventually add to my flock of ( 2 Barred Rocks, Golden Laced Wayandotte, Cochin Bantam, Buff Orphington, and blue splash cochin bantam roo).. I've been keep them in a wide 15 gallon tub with chick starter feed, water and of course their heat that's always between 90°-95° as they are in their first week. I just want to make sure that im doing everything correctly. I will raise my heat lamp up -5° next monday and repeat pattern every week -5°. At what point should I put them in their own run and get them out of the 15 gallon tub? I assume as they just grow out of it? Im putting chicken wire up dividing my coop. So the birds can all get use to eachother until my chicks reach about 4 months I was told? Surprisingly all my chicks seem healthy! No pasty butt, and they all eat/drink/sleep/peep/ all day. Any other tips/tricks/ would be great to know! Im thirsty for knowledge as I rescued my existing flock when they all had just started to lay so i dont know much about the chick/pullet stages!! Thanks!
