So my 8 little chicks will be turning 4 weeks tomorrow and I am at a loss at what milestones they should be hitting at this point. They've almost feathered out completely besides their heads and random blotches all over their bodies, are active and eating well, go on outings to the backyard every day, and have been upgraded to a 6.5ftx2.5ft brooder. What's should I expect in the coming weeks? When do I take away the heat lamp? When can they move into the coop? Is there a weekly growth/development chart somewhere I can look over? Haha I feel like this is a weird question...but I was just wondering what I should be looking forward to! Thanks
