So I noticed earlier this week one of the wyandottes laid an egg with no shell, just the membrane. I didn't know who because they were both standing by it eating it. Researched it a bit and most peope said it happens occasionally but I've put out some extra calcium source just in case. Then yesterday I noticed 2 eggs laid in the coop, one from the americauna/easter egger and a wyandotte egg that was thin shelled and cracked already. I'm thinking I need to go out and get calcium supplements now, like oyster shells right? Secon problem: My gold-laced wyandotte is shedding feather like crazy. I've noticed as the weeks gone on more and more feather about but when I looked at her this morning I've realized she's lost just about all her tail feathers. She doesn't act sick, is eating, scratching, etc.....I'm now think she's the one laying the "soft" eggs. The only things that have changed this summer is that we have 6 pullets (teenagers) in the coop/run with them now. But they're still a bit afraid of the hens so they don't bother them. It's aso quite hot, being in Austin, TX (triple digits last week and this week) but we had an even hotter summer last year when they were chicks. They've been free ranging all day, all summer since I'm a school teacher, but am going back soon so they're going to only be able to free range when I get home. (I'v had hawk attacks so I let them out when I'm able to watch outside and have ears for the alarm). Any suggestions? I lost my dark brahma a few weeks ago as well but I was out of town so I'm not sure why she died, my roommate had called me the night before saying she looked dull and wouldn't eat. Everyone else seems fine.
