I have been trying to hatch chicks for years, with only one success in an incubator, but that chick died. So, I bought 3 Cochin chicks last spring. One went broody a month ago, so I moved her into a cage in our heated garage and she was such a faithful setter. She started with two eggs, then I added two more the next day and then two more the next day. She had six total. She got up less than once a day, and then at the end, she wasn't getting up at all, so I put her food and water where she could reach while sitting. I was sure they would hatch and none did! Today, I put her back in the coop and opened the eggs. There was at least one completely formed chick and then some partially formed others. I want to try again, but I want it to work! What can I do differtly next time? Since she's new to this, should I start with less eggs, 4 maybe?
