Hi everyone! I have a 2 week old chick that has a very swollen, squishy lump on her chest. Its been like this for 2 days now. Anyone know what it could be or what I can do about it? I have 9 other chicks & none of them have whatever this is. Shes eating, drinking & walking fine, they were vaccinated for Marek's by the hatchery before shipping. The bedding is pine shavings, they're eating 20% chick starter/grower feed, I change the water multiple times a day & they do not get treats or anything other than feed to eat. Please help, I'd hate to think she's in pain & I definitely don't want to lose her. TIA!
